Color contouring like this, with colors matching or coordinating with the costume and wig color. Would be quick and easy, but dramatic. Would want to darken/enhance brows and lashes as well as add some coral-hued blush and lipcolor for balance and whimsy.
Nars Orgasm Blush. Had some applied at a NARS counter. Asked what colour it was and the answer was this. Comparing to all my orgasm dupes the original is much more pink and flattering. And lasts longer on cheeks.
