Kelly Osbourne looks fab in Mary Katrantzou

Sometimes an outfit is so good it makes us want to stand up and applaud. So please join us in getting to your feet for Kelly Osbourne.

The TV presenter was out in LA last night at the 75th anniversary of Kreiss, the Californian luxury home furnishers, and not only did she debut a new shade of purple hair, but she matched it with purple lips and nails and topped the outfit off with a stunning floral Mary Katrantzou dress. The peep toe heels completed the look.

Kelly's not the only person to go purple recently, following hot on the heels of Katy Perry and Jessie J. Maybe the girls have been sharing colour tips?
