www.bluefly.com has a lot of new product, particularly in the women's section. They seem to be improving, although make sure you check for the stuff on YOOX, as they have some of the same stuff at often much lower prices (Dior Homme, Ann Demeulemeester, and Dolce & Gabbana are a few that I happened to notice). It probably isn't necessary for all the guys here to check it out at the moment, but I'd suggest it for female fans of Marni, Miu Miu, Galliano, Gucci, bla bla bla, etc...
Just go through the designer list. They've added a lot of them.
