Ii was a lil big for the size, my daughter wears like a 12 in Justice clothes, I got her that size for this costume and it was baggy and a lil too long, but then snug at the shoulders where it hooks, so a smaller size wouldnt have fit her anyways. But it was super cute and unique, there was nothing like it in the mall so I was happy to get her something  online noone else had. She loved it!!
