This is a good costume with bright colours and a shiny metallic skirt. I find it fits a bit on the large size, and has quite a bit of stretch to it. If you're at the lower range of a size, I'd recommend getting a size down.

The back opens from the waist to the neck and is secured by Velcro. The Velcro strips have wide spaces between them, and even though the costume fit loosely I think I'll put a zipper down the back so there's no gaping.
