Thank you for viewing this item. I wore this once for a graduation ceremony. It has a ribbon-like knot at the waist. There is no zipper in the back, and the waist is elastic, so even though I usually wear a size L, it was easy to put on and take off, and it wasn't constricting. It's a design that seems like it could be worn casually as well as for formal occasions.
