I ordered this tutu in white for my daughter's hip hop recital. She is only 6, not a big girl and I ordered a M/L. Glad I did. It's short and fits around the waist just fine. I think the S would've been WAY too small!!! But it's exactly what we wanted.
This skirt is easy and adds a nice touch for a low key performance. However, the XXS and ML sizes are not the same length, so you can tell at a glance who is wearing what size and the dancers don't match.
