What the others have said, it's about how you feel in it!
Its A nice dress.
it wouldn't suit me because I'm a) busty and most dresses make me look matronly, but that style especially B) I have a big tummy and most dresses make me look like a side lamp
but that's shape not size
try it on & see how you think you look/feel.
i have to go by 'look' in the mirror. Because. I love the way dresses feel! But knowing how dreadful they look I just can't bring myself to wear them.
