The costume was satisfactory-- cheap material of course, but not a big deal.  The wig had hairnets over the two side buns and when you took them off, the buns sort of fell apart.  I didn't have the time to fix them, just tried to stick on bobby pins to hold them as well as I could. I think it's the only Princess Leia costume on the market, so it's not like you have a choice.  My advice would be take the wig out of its hairnet and style it ahead of time.
