Since Halloween falls on a Monday this year, a lot of parties were planned for this past weekend. Celebs, fashion people, and various reality TV riff-raff were all out in full force with their costumes blazing. From strippers to princesses, the costumes ran the gamut.

Oh, and of course there was Heidi Klum (left) who went as a…medical school cadaver? Anatomy drawing? Flaying victim? Klum told People her costume was called “visible woman” and described it as “kind of like a dead body with the first layer of skin ripped off…it’s basically like me naked.”
