Wizard Flat Black

Okay, I`m wearing leggings and a shirtdress to shakespeare theater. The shirtdress is yellow and black with thin lines of silver/gray is long enough to cover my bottom and not look skankish. I am also wearing black leggings that are footless [stops at my ankles]. What htype of shoes would be better. Flats (either yellow or black. i haven't decided). Or heels?If I wear heels they are gonna be silver. But the thing is they are closed toed and look like Dorothy's from the wizard of oz. Exept they're silver/glittery instead of red. So which? The yellow or black flats...or the sparkly closed toed heels?
