I bought this for a costume and it looked really awesome!  It adds a lot of volume to the skirt and made it look a lot cooler.  The few drawbacks is that it is only one size, so if you're a plus size (like me), it is a bit too tight at the waist.  I tried to stretch out the elastic a little bit so that it was more comfortable, and that worked out so-so.  The only other drawback is that it can get a little itchy if you're wearing it over bare skin.  I'd recommend wearing leggings or tights underneath it to minimize the itch.  Otherwise, this was a great addition to the costume and came at an affordable price!
