Please tell me which shoes and jewelry to wear with this outfit-its a formal company party?

silver heels would look nice with the silver belt. as for jewelry, keep it simple. maybe a bangle bracelet and some small hoop earrings; a necklace might compete too much with the belt. if you wanted to wear a necklace, try a black belt and a pair of red heels to pop the outfit. i'm sure you'll look great. have fun!
