McQueen - Scary! Still giving me the heebie jeebies. Galliano and Yohji? Fright Night!!!
But, I actually kinda dug the Dior and YSL looks. Not in a "you must replicate this look kind of way" but more as inspiration. I think it would look kinda cool to layer a couple (three, max!) of those headbands-with-teeth thingies, but that's just me. And the Dior - pure fantasy femme fatale. :)
