JUST CAVALLI V-Neck Metallic Studded Sheer Sleeve Gown / NWT

Exquisite 2018 Just Cavalli Evening Gown. Perfect for prom, a wedding, evening event. Silver Studded Beaded Accent Design over a nude/blush bodice. Metallic silver/black sheer long sleeves. V-Neck + V-back design. Concealed Zip Closure at Side. IT Size 40 equates roughly to a US 4 or S. Approximate Measurements: Bust 30.5" Waist 25.5" Hip 28.5" Sleeve Length 20" Length 65". Fabric: 92% Viscose, 8% Elastane; Lining 100% Polyamide; Combo 88% Polyamide, 12% Metal; Combo 2 82% Polyamide, 18% Elastane. Material is VERY stretchy, so I imagine it could easily accommodate a general US size 2-6. Bought new at a local Los Angeles auction, never worn, tags still on, smoke-free home. I'm in love with this rare gem but I really need to downsize :( Note: same model dress pictured in a black bodice for reference only.
