I thought that I was done with sewing exercise clothes but this remnant was quick to sew up this afternoon, and I wanted a quick project that didn't need a change in overlocker threads.
I got the idea from this drape drape project. I think mine is shorter and possibly less voluminous, because I was working with a remnant.
I started with a tank pattern (I used Vogue 2946 and cut away the back armholes to give more of a racer back shape). Then I extended the underarm horizontally, as much as the fabric width would allow.
I'm planning on wearing it over some of the sports crop tops I made. It is very airy, which will be good in summer, but doesn't offer any sun protection, so it will be more for indoor exercise. It would look great layered over a black long-sleeved tee, but I don't have one of those.
