White lace dress

Purchased this dress for my bridal shower. It's too big for me. It was purchased off VICI for $58 +shipping. It's extremely well made, very nice. White lace over nude lining. I'm sad it just doesn't fit and I didn't have time to exchange it before my bridal shower. Size medium (6) I'm 5'5 and 120 pounds. If I had a bigger chest it would've been great. Fits like a medium. I normally wear a small or medium but was between sizes on their size chart. I Shouldve sized down.
