Zimmermann Dress - Wonderland Strapless Shell-Trimmed Gown

This is a Zimmermann size 3 (fits like US 10; Zimmermann claims a 3 fits like a 10/12 but I am typically that size and this did not fit so maybe more like an 8/10). In excellent condition with no signs of wear (I just ordered from TheRealReal and am selling here because unfortunately the dress didn't fit; these are all the descriptions from TheRealReal- I am happy to show you my TheRealReal receipt for proof of anything). Measurements: Bust: 31.75" Waist: 30" Hip: 40.5" Length: 45"
