Designed to be fitted throughout. Non-adjustable straps, cowl neckline. Side ruching. This is a lightweight silk charmeuse fabric - 100% silk. Dry clean only. The model is wearing a size 2 and is 5'8", 23" waist, 35.5" hips, 30" bust. Perfect for weddings! Never worn, it was too large for me but I missed the return window
