The SIA dress is simply elegant. This floor length dress with the knotted top and waist sash detail is the destination wedding, engagement dinner, reception party and all round go to partner to look just right for the occasion. NWT - Dress is a US Size 16 but fits more like a 12/14. Could fit a size 16 if you don’t have wide hips/butt. Couldn’t not zip it up on me. Would be perfect for brides for welcome party/rehearsal dinner/after party/honeymoon!
