Margaery Tyrell would never wear this.
But that's because she lives in a fictional kingdom set several hundred years ago where all the women either wore heavy layered gowns or walked around naked for no reason.

The Game of Thrones star matched her magenta purse to her frock, but picked strappy, caramel-toned sandals for her feet.
Hmm, Margaery might actually like those shoes! Don't you think?
