NWOT Embellished Crystal Dress

Bought this on Poshmark BRAND NEW told it was a small however that wasn't the case it's a size 8? The seller then told me after its an Australian size 8 but supposed to be a small? Worst case it didn't fit me at all way too big for me. Beautiful dress with a sweetheart neckline and BRAND NEW👗✨💎 take it off my hands ladies 💕
