I bought the small I am 5'4 105 and it is bigger than I would have liked. Otherwise I absolutely love this jumpsuit! Like previous reviewers stated, you can dress it up or down.

THE ONLY DOWNSIDE FOR ME IS THE ABSENCE OF A BUTTON BEHIND. OVERALL IT IS A REALLY NICE CASUAL/OUTING JUMPSUIT.

I LOVE this romper! I wore it for the first time yesterday - just to run errands - and I received so many compliments! Even my husband and kids noticed I was wearing something different (no small feat, as you moms know). I purchased a large, but probably could have gone down a size (I'm 5'3 and about 135 lbs, for reference), but I don't mind that it's a little loose. You can definitely wear this casual or dress it up with some heels and jewelry.
