I don't know, I just think she looks a little dishevelled, but probably just made a mistake with the dress - i'm sure it wasn't see-through IRL, but just came that way with the flash (you guys have seen evidence of this with other paparazzi pics, i'm sure)
i know i've seen pics of my friends where their bra is showing but that night I couldn't see it at all, you know what i mean? i don't mind her makeup either.
