Per Shopbob “Ruched sides create a ripple effect on this one-shoulder AIR by alice + olivia mini dress. Nonslip rubber binding at top hem. Exposed side zip. Mesh lining. Fabric: Slinky jersey. Shell: 95% polyester/5% elastane. Lining: 80% nylon/20% elastane.” This dress has never been worn, only tried on. It’s super sexy and forgiving because of the ruching. Size 8 was a little tight on my upper body but I have broad shoulders. I’m a 36B-30-37. Please let me know if you have any questions :)
