I don't know why this site has such terrible reviews!
I've ordered off here at least 15 times and nothing has ever gone wrong. Most of the items I purchase are on sale, (very cheap), but I've never ever been unsatisfied with the quality of their clothing. It fits great, looks great and I always get the most compliments when I wear clothes purchased from Nasty Gal. I'm addicted.
Their return policy is also great. The one time an order didn't fit, I used the return slips they enclosed in the parcel and sent it back. They were friendly to deal with and quick to respond to my queries. I highly recommend it.
