I bought this for my St. Pattys day costume...I'm a size 3 and it fits loose that's why I didn't give it five stars.  I'm going to have to pin it...just be aware if your smaller it may not fit snuggly.  The waistband should be about 1-2 inches less.  It's one size fits all...but that's not the case. But it's made nicely and it's super short...but that's what I wanted!
