A beautiful pair of heels for a party, but what to wear with them?!?

They're a silver glitter, so in the light they sparkle all different colours. Anyway, I'm going to a party in a few days time, and it's a bit dressy, not over the top or anything, but I have no idea what to wear with the shoes! So far I'm thinking a black pencil skirt and a white oversized print t-shirt? That's all I can think of! Does anyone have any suggestions for what to wear? Thank you! xo
