The perfect dress for an engagement party! Received so many compliments and was so comfy to wear all night. I thought I’d feel restricted to move my arms bc of the straps but wasn’t the case at all ! Size large but runs a little small in the chest. It doesn’t have somewhat a built in bandeau. I still wore a bra just to keep my shapewear in place! Satin 100% polyester. Adjustable shoulder straps and has a zipper.
