Lulu Guinness

Lulu Guinness celebrated her 20th year in the biz with a party at London's Victoria & Albert Museum yesterday, and we hope she remembered to RSVP the plus-one that is her dress. The quirky-but-cute designer celebrated with the likes of Katy Perry and Sophie Ellis Bextor at the event, where we spotted one of the orangest skirts we've ever seen.
