This is a proper wrap dress so can tighten or loosen as desired.

It does have a top string to stop it from coming apart at the top but to be honest I didn't really find it necessary.

I love the material! It's kind of like a stretchy suedette kind of feel. Very comfy to wear all day and warm without being hot. Comfy all over including the arms and a good length.

I got the size 22 and am happy with the fit. It will definitely be on rotation in my wardrobe.
Highly recommend!
