I decided I needed a bandeau to go with a lime green lace shirt my mom bought for me at Target. I used some fabric I had left over from my neon green/yellow dress. I double layered the fabric so it wouldn't be see-through and used 1/2" elastic around the top and bottom of the bandeau. This is the link to a tutorial on how to sew a bandeau. I didn't really follow it; I sort of just did my own thing.
