^ Even if that is true, it's not something she can change. "Hilary knows how to look good in leggings" implies that she knows how to accessorize / work them into an outfit better... when really it's just that her body looks better in them and that has nothing to do with her sense of style at all.
Anyway, I'm kind of tired of the whole oversized tanktop/t-shirt + leggings trend in general... somebody please invent something new. :|
