It says XL but I took up the sides so it would fit my small daughter.

So it’s sewn like a small/medium but I didn’t cut anything so if you like it and wear XL all you have to do is take out the two seams on the body or if you wear small you can wear it as is. My daughter went as Tinker Bell note the picture. So with seams in (small) seams out XL. Leotard, tutu, wings.
