I normally get size 14's from other manufacturers but with quality like this I got my normal size 12 and it's fits perfectly. It's stretchy so plenty room for bums and tums. No zip to fiddle on with, just a little button at back of neck.
Fantastic dress love it the material is stretchy so comfortable to wear. Wore it to my Christmas party night had dinner then a dance got many compliments. Highly recommend this as your alternative little black dress .
