I made another Onyx blazer, this one hip length in charcoal grey ponte (charming heather legacy ponte from Zelouf) with pockets. I tweaked the pattern some more before I cut it out, this time to add a simple sloped shoulder adjustment (in addition to the round-back adjustment and small-bust adjustment I made on my purple cropped Onyx). I noticed that when I raised my shoulders (as in a shrug) the drag lines I saw on the back of my purple Onyx mostly disappeared. So I lowered the outside point of the shoulder by .75 inch and adjusted the shoulder line on the center and side front and back pieces accordingly. Then, I lowered the armscyes to meet the lowered shoulder point, ensuring that the size of the arm openings did not change. This reduced the excess fabric from the shoulder area that had been pooling around the armscye and helped reduce drag lines on the back. The fit of the back is now about as good as I’m going to get so I will stop tweaking and use this going forward. I made a size 4 hip length, shortened by two inches. I reduced the height of the pockets by only about .5 inches and made them a tad narrower to fit the shortened side-front pieces.

For the purple Onyx, I cut the facing pieces using the front-center pattern piece so that I could sew them down when I top stitched the front seams. I used a lightweight fusible interfacing with no stretch. I noticed that the interfaced facing shrunk a little bit, making it more difficult to attach smoothly, but I made it work. However, on the grey ponte, the lightweight interfacing was a complete disaster. When I clipped the facing to the front center pieces, I found the facing was about an inch shorter. I tried to make it work but it was clearly not happening. Then I remembered that I had tricot interfacing (Superpunch Fusi-Knit White HTC1300), which has some stretch to it. So I cut new facing pieces and fused the tricot interfacing on, with the stretch running vertically. This time the facing did not shrink and everything went together the way it was supposed to! This was a great lesson in selecting the right interfacing for the job.

I did most of the sewing on my serger but I used my sewing machine with my quarter-inch edge foot to do the stay stitching, basting, and top stitch the front and back seams. I used my regular edge foot to top-stitch the tops of the pockets. I sewed the arms to the bodice with my sewing machine before serging, and I made sure to start and stop the serged seam in the armpit. As with the purple Onyx, I sewed the center back seam with my sewing machine, pressed it open, and then topstitched a quarter inch on either side of the back seam. This makes for a nice flat seam that looks very nice.

I used fusible hem tape on the bottom hem and sleeve hems before sewing. I also used it to hold the facing edge in place before top-stitching. I used a glue stick in a few places to keep pieces aligned before sewing.

Ponte is a comfortable fabric to wear, washes well, and resists wrinkles, snags, and pills. The charcoal grey should go well with a lot of things and I expect I will wear this one a lot. The pockets are a nice convenience too, although I probably won’t routinely put my phone or anything heavy in them as it will stretch the ponte. The hip length is just long enough to cover an untucked shirt, which makes it a pretty versatile length to wear with a lot of things. Here I am modeling it with black ponte PE Urban Wide leg pants and a Sinclair Bondi top in plum brushed sweater knit. The jacket also looks great with the PE Urban Wide leg pants I made previously in the same charming heather ponte fabric.

Summary of modifications to size 4 hip-length pattern with pockets:

• Small-bust adjustment (performed by redrawing the inner curve on the side-front pieces to have less of a contour and then shortening the center front pieces to match the length of the new curve)
• Sloped-shoulder adjustment (3/4 inch)
• Round-back adjustments (2 5/8-inch adjustments near top and bottom of arscye)
• Deepen back neckline by about 3/4 inch and adjust back facing
• Shorten bottom hem by 2 inches
• Shorten sleeves by 2 inches
• Shorten pockets by 1/2 inch and adjust width to match width at hem line
• Cut facing and interfacing from front-center pieces instead of facing pieces

After making my tulip Onyx Blazer, I went down a rabbit hole of fitting adjustments. My first Boo & Lu Onyx fit reasonably well, but seemed too loose in the back. After much experimentation and sewing up an entire muslin of the hip-length version with pockets out of an old couch cover, I came to the conclusion that 1) a size 4 would fit me better than the size 6 that I sewed and 2) I need a round back adjustment. Although I have recently also discovered that I need sloped shoulders, broad shoulders, and sway back adjustments on some patterns, it wasn’t clear that these were needed here so I decided to proceed with my cropped purple scuba suede Onyx without these adjustments, although now I am reconsidering.

I finished the blazer yesterday and it was warm enough this morning to snap a few photos outside before I walked to work.

I started with the size 4 pattern, opened it in Affinity Designer, and added two 5/8-in round back adjustments near the top and bottom of the armscye. I had added a small-bust adjustment to the size 6 version that was a bit difficult to execute and did not result in the contour I really wanted. I read in the Boo & Lu Facebook group about an alternative SBA that involved simply redrawing the inner curve on the side-front pieces to have less of a contour, and then shortening the center front pieces to match the length of the new curve. This was easy to implement. I also slightly lowered the back neck line (I find this more comfortable, in part due to the round back issue) and adjusted the neck facing accordingly. I used the crop length and extended it by two inches so that it wouldn’t be quite so short. I shortened the sleeves by two inches because I am short and have short arms. Finally, instead of using the front facing pieces, I cut extra center front pieces to use as facing. This allowed me to solve the problem of the front facings not lying flat by stitching them down when I top stitched all the seam joining the side and center front pieces.

I cut out my cropped onyx from leftover purple scuba suede I had used to make a Sinclair Alana dress two years ago. This fabric is thick and stretchy, so wasn’t the easiest to work with. I fused ultra-light interfacing to the facing pieces, which stabilized them. However, even though I had stay-stitched as recommended, it was still difficult to join the facing pieces to the front pieces that did not have interfacings as the front pieces had a tendency to stretch more than the facing pieces I was trying to match them with. I had to unpick and resew one side twice until I got it right. I also wasn’t able to achieve a really sharp edge. After it was all sewn together I topstitched along the front and back seams, using my quarter-inch edge foot as a guide. My first attempt at this was a mess — the lines weren’t straight and the facing didn’t fully catch in the stitching. I unpicked the top stitching and used Steam-a-Seam 2 fusible tape to glue the edge of the facing to the inside seam it was supposed to align with. Then I carefully redid the stitching and it came out much better.

I’m pretty happy with the end result. It fits better than my first Onyx and the fabric is fun. The length works really well with dresses, but as you can see here it also works with pants. I don’t think this length looks as good with shirts not tucked in though, so I’ll probably make a longer one. It does go perfectly with the dress I made from the same fabric. The rounded back adjustment and lower back neck were a good improvement that makes the blazer more comfortable to wear and keep the back closer to my body. I feel like there is still something more I should be doing on the side back pieces to reduce the drag lines pointing to my armpits (which were not as prominent on my muslin, but maybe because it was made from a woven fabric with less drape). Maybe I do need a sloped shoulder adjustment? Also note that the front is fairly open in the photos and so you can see some fabric bunching under the right arm. When I pull the front pieces closer together that goes away.

Even though I didn’t do any of the fancy seam finishes, I do like how the seams look on the inside, sewn with my serger and neatly top-stitched in place. I did sew the center back seam on my sewing machine and serged the edges so that I could press it open.

Now that I have a collarless blazer pattern that fits pretty well, I want to make more! (But maybe keep trying to address the back drag lines with a sloped shoulder adjustment?) Next up, the hip-length version with pockets.

I’ve collected a few Boo & Lu PDF sewing patterns but had not gotten around to sewing any of them until now. I’ve been thinking about sewing up the Onyx blazer since it came out because it has princess seams for nice shaping, can be made in either knit or woven fabrics, and it is collarless. I have a closet full of blazers with collars, but over the past few years have found that blazer collars are increasingly uncomfortable on the back of my neck so I’m looking to expand my collection of collarless blazers, which it seems are harder to find (both ready made and in patterns). The Onyx also has several options, including a hip-length version with optional pockets, a peplum version, a tulip-bottom version, and a cropped version. I may eventually try them all. The pattern also includes options for bows on the back of the blazer. While they are cute, I am less likely to add them to a blazer for me to wear. There is a kid’s version of this pattern and I think the bows would be super cute on a blazer for a child.

I started with the tulip version since it looked like a style I would likely wear a lot and it looked like I had enough leftover black ponte fabric from a pair of pants to make it. It has a lot of pieces, but they are all fairly small, so I was able to make good use of some of the scraps. This version requires only a little bit more than a yard of fabric (assuming ~58 inch width) in my size. I made a size 6, with a 1/2-inch small bust adjustment and sleeves shortened by 2 inches. (And it matches the pants — PE Walk Boldly — so now I have a suit!)

The pattern includes a lot of instructions and notes, including suggestions for a full bust adjustment and small bust adjustment. In my case, I needed a small bust adjustment, something I had never attempted previously. The pattern has step-by-step instructions for the full bust adjustment, and then suggests doing the opposite for a small-bust adjustment. Most online tutorials take a similar approach. Bust adjustments are somewhat complicated as they involve making adjustments to a flat pattern piece designed to fit a round part of the body. Generally, you take paper pattern pieces and cut them apart and tape them back together. Since I am working with projected PDF files, I figured I should be able to do this electronically in Affinity Designer. I found an AD tutorial that explained how to do full bust adjustments. After watching the tutorial I attempted to follow the steps on my own, except the opposite. I realized that my AD skills are still fairly poor, but I learned quite a few things about using AD in the process — I should really watch more AD tutorials when I get a chance! I had trouble getting my head around how to execute this adjustment in the opposite direction, but after a lot of puzzling, I eventually figured it out and completed an adjustment that seems to have worked out ok.

I projected my pattern pieces with the adjustment and cut out the Onyx tulip pattern with no other adjustments. I knew the sleeves would be too long (they always are unless the pattern comes in petite sizes) but decided to cut the full length and adjust the sleeves on the finished garment after I tried it on.

The pattern has 3/8-inch seam allowances and offers five options for finishing the seam allowances. I chose the easiest, which was to just surge all the seams with a 1/4 seam allowance, trimming off 1/8-inch as I went. Since ponte is a knit, this works well and with all black fabric and black thread, it looks fairly neat too, although of course not nearly as nice as a bound seam allowance. The main downside is that ponte is fairly thick fabric and it would have been nice to be able to press some of the seams open rather than having them pressed together to one side. I think if I make another Onyx in ponte or other heavy fabric I might take the time to serge all the edges (without trimming) that will be seamed and then sew the 3/8-inch seam allowance on my sewing machine. But I am somewhat of a lazy sewist, so then again I might not!

For the most part, the blazer went together fairly easily, but I struggled a bit with attaching the sleeves. The pattern has great instructions and everything is nicely marked, but I still somehow clipped everything together backward, but realized something was off before sewing. I eventually figured it out, clipped everything together properly, and basted it with my sewing machine. Then I serged it together, but made the mistake of starting and stopping at the shoulder, which made it more difficult to smooth out the shoulder line. Next time I will start and stop in the armpit — or maybe just do this on my sewing machine and skip the serging.

Another problem I ran into was one of the front princess seams not lying as smoothly as I wanted. At first I thought it was a pressing issue, but after pressing again I realized one of my seams actually had an unwanted dip in it — it was only off by about an eighth of an inch, but it was enough to cause a noticeable bump in the princess seam right in the middle of the bust line. I resewed about 3 inches of seam on the correct seam line and that fixed the problem.

The instructions noted that the facings might not stay smoothly in place, and indeed mine did not. I tried their suggestion of fusing them in place with a few small pieces of fusible hem tape, and that did the trick. The interfacing I used on my facings was some leftovers from another project that I grabbed, and it was more of a medium weight than a lightweight interfacing. Next time I might try a lighter-weight interfacing.

Attaching the tulip pieces was fairly straightforward except for lining the corner of the tulip up with the front facing. Perhaps due to my heavy fabric and interfacing, I could not get the tulip corner aligned perfectly. I did try unpicking a few stitches at the bottom of the facing and clipping the corner, but it is not aligned as well as I would have liked. This is one downside of the tulip version that should not be an issue in the cropped or hip-length version of this pattern.

I made good use of several feet on my Bernina sewing machine. The patchwork foot with guide made the quarter-inch top stitching around the edges very easy. I also used my darning foot to stitch in the ditch to hold the facings down and my edgestitch foot for the sleeve hems.

Overall, I liked the instructions in the pattern and found the suggestions and photos helpful. I did find a couple of things that are probably errors. On page 11 the finished measurements for the four variations appear to be mislabelled. The crop version has the longest length, but clearly it should be the shortest. Even accounting for that, my finished garment was about an inch shorter than the measurements would suggest. The other error is on page 71 where dark lines are drawn on a photo of the facing to show the raw edges finished with a serger. I believe the lines on the top of the neck facing should be on the bottom of the neck facing.

The blazer fits me well and goes well with both pants and dresses. It has a really nice tailored look, but is less work than a fully lined tailored blazer. I expect I will wear it a lot. When I took photos of the back (see below with PE Walk Boldly pants in black and PE Urban Wide Leg pants in purple, Sinclair Bondi top) I did notice some drag lines beneath the back shoulders. After pondering the cause, I believe it is likely a shoulder slope issue so I plan to try a muslin with a sloped shoulder adjustment and see if it helps before I make another one.

I’m looking forward to making more Onyx blazers. I’m planning out a ponte suit in a bright color with matching wide-leg pants. I’ve already worked out how to cut the blazer and the pants out together from 3 yards of fabric. I love the length on the tulip version, but would also like to try the hip-length with pockets (I will certainly have to shorten it though). The cropped length is fairly short, but I might make it specifically to wear with a dress, and I might round the front corner more similar to the tulip version. The peplum version is also cute, although wonder if it will be too poofy around my waist. I could also see lengthening the cropped version to be the same length as the tulip version…. so many options!

(It’s too cold outside for outdoor photos now so will have to make due with indoor fashion shoots. I’ll try to improve the lighting though.)
