^SJP is fabulous, and that dress was amazing. But as a human specimen, Hugh is in a league of his own.
But even on Hugh, the blue and yellow Wolverine costume would *not* look good on screen. Tan and brown.. maybe. I'm personally a fan of the X-Force look, but that's not iconic enough to make an appearance in a film, me thinks.
Cos a costume would be a nice nod to the fans, but that's all it is. Nobody needs to see a costume to actually recognize the character Wolverine.
