I second Drifter's suggestion. I've done Dagger, from Marvel's Cloak & Dagger, and I used fashion tape to keep her costume in line. It worked very well all day, even in areas with more tension, such as around the bust. They were also very small and easy to carry in my emergency bag in case one lost its stickiness.
