This project was sort of a personal challenge. I've been making a lot of quick and easy spandex items on my serger this year, and wanted to see if I could make something more complex. A catsuit seemed like a good candidate, and I can use it for costumes, as long underwear, etc.
I own a catsuit in plain black so I started by tracing it to make a pattern. I figured tracing would work because there's a lot of leeway in getting the fit right with a stretchy fabric. The basic suit is 8 pieces: two front, one back, collar, a crotch gusset cut in half for a zipper, and sleeves. You might notice my suit has a couple more pieces, but I'll get to that in a minute.
Since this was sort of a "trial run" of this pattern, I didn't want to spend a lot on fabric. This was the best I could find that didn't have an obnoxious print and was reasonably priced, even though the stripes made it a little more challenging to work with.
