Was concerned this would only fit a tiny ballerina adult, but its one size, and with elastic it actually has a lot of give to it. I'm average sized and it fits just fine. Word of warning though, its transparent, see though.
The fabric of the tutu is durable and the seams are well constructed. It is even fluffier than the picture conveys. It's very pretty and an object of desire in my pole dancing class. I've also used it for modern dance as well. It's a lot of fun to wear.
