They look beautiful to me but I'm not a guy. So long as the white isn't bright white I don't think they will look cartoonish/costume-y. I also think that they are a pair of shoes that will look better worn in a bit so I wouldn't worry about them - quite decadent, McQueen should never be pristine ;0
Thanks papertiger.
I've decided that if i took so long to contemplate a purchase, it probably isn't worth it in the first place.
I think if I ever get another exotic, it will probably be a small accent piece...like a SLG or bracelet.
