This is great. I bought it for a fancy dress party (of course) and being female but a bit of a tomboy, I don't really like the traditional skin tight outfits that are usually targeted at women. So this was perfect for me and with minimal effort! I wear a 16/18 in jeans and this fit me fine but without much extra room so I personally wouldn't recommend it if you wear a larger size. You step into it and pull it up and it has a drawstring around the waist/hips. Your feet come out of the bottom where there is an elastic strap that goes across under your foot to keep the "feet" in place, so you have to wear shoes/ trainers on your feet. I wear a size 7 shoe and the feet covered my shoes fine but they did keep riding up a bit from time to time revealing my shoes (despite having the elastic strap under foot) so I would recommend wearing dark shoes/ trainers so it's not really noticeable. It's quite a wide costume (I don't mean as in fit, I mean because of the fake legs) so you'll find you'll have to go sideways if trying to get through a narrow space. Would definitely recommend
