Britney and Ashley both donned the hot pink sheer Brian Lichtenberg mini dress, but to be fair Brit sported it first back in May. She made her X Factor debut and definitely impressed in the dress, paired with a casual hairdo and black stacked pumps. Ashley chose the bright mini just a few days ago the at the Wenn in Vegas. Ashley also went for a casual hairdo, and paired her dress with nude pumps and a cute purse. And Ashley gets points for tweeting a hot twitpic of herself in the dress.
