My daughter joined a fire spinning club and has to wear 95% cotton or wool clothing while playing with fire. Personally, I would go with tight jeans in this situation, but she doesn’t like to wear jeans. I previously made her a pair of black cotton french terry pants (which apparently I never photographed), but a few weeks ago she emailed me that she wanted a black skirt, and sent a sketch of what she had in mind. She wanted a midi-length skirt with a slit on the right side, but in several inches from the side seam so that she could dance in it, ideally pockets, and a waistband that wouldn’t move around. She wanted the skirt to have a little bit of swish, but not so much fabric that it would be a big fire hazard.

I decided to use the Pattern Emporium Heartlight skirt pattern, which I previously used to make a short skirt for myself, modified to have pockets. I used the size AU 10 pattern with AU 8 waistband, just as I had made for myself. I used about 2 yards of 95% cotton/25% spandex black jersey fabric.
To achieve the slit I split the front panel of the skirt into three pieces. I drafted pocket bags that I could anchor between the side seam and the interior front seams, with top diagonal pocket openings. I’m showing the front pattern piece in the figure below, divided into three, with the pocket pieces laid over it. The pockets fold up at the green dashed line. (I know she only asked for one pocket, but once I figured out that I could anchor them in, I decided to give her two.)

I sewed up the left seam but only sewed the top 10 inches of the right seam and then serged the raw edge of both sides of the slit and top-stitched them down. After she tried it on and found the waist not as secure as she wanted, I threaded elastic into the waistband.
She says it is exactly what she wanted for her fire spinning performances and she likes it so much that she will wear it even when she is not performing.
