Teal Oleg Cassini dress

Worn only once as a bm at my sister's wedding, dress is in mint condition. It's ideal to wear to a wedding or a fancy dinner. Has a sheen to the fabric making it look expensive. Zipper closure in the back with a sewn-in underdress. No tag on the dress but I would say its a 2-4 or a size small. I'm 5”3 and length comes to my knee.
