Balmain black bodycon shoulder pad structured dress (too large on me)

This classic black Balmain dress features stylish gold button accents on the shoulders with gold zip up back. Gorgeous dress and perfect for any occasion. Its sleek design offers a flattering fit, making it a must-have addition to your wardrobe. There is no size tag and I cannot find it anywhere in my house. I purchased at Saks and planned to have altered to fit better but never did. I’m a size 2-4, XS-S and this is slightly large on me (with lots of stretch!) I think it would probably best fit a size 8 but that could vary due to fabric stretch and desired fit. Flawless fabric, like-new condition!
