We just can't get enough of our celebrity fash-offs and one that definitely caught us off guard was super Erin O'Connor in the same Matthew Williamson number as WAG - turned-style icon Cheryl Cole. The pint-size pop singer handpicked the blue sequin dress (straight off his SS09 catwalk) during a shopping trip with NBF Matthew Williamson for one of her XFactor shows only a couple of weeks ago - and then we spotted Erin O'Connor attending the BFA after-party in the same dress. But who wore it best? Vote now.
