Calling all fashionistas - Style It Light are giving you the chance to win VIP tickets to the Clothes Show Live, as well as the opportunity to see your style recreated on the show catwalk!
All you have to do is post a picture of yourself on Instagram in a super stylish outfit, using the hashtag #DietCokeCSL, and the best will be chosen by fashion experts from InStyle, Marie Claire and Look as the victors of the Diet Coke Style Showdown!
You can wear whatever you want for the snap as long as it's inspired by one of these fab fashion themes – fashionista, romantic or rock chick – so there’s plenty of room to express your own style.
The three most stylish people from each category will win VIP passes for two to the show, as well as travel, accommodation and the chance to see their outfit on the catwalk. 18 runners-up will also receive tickets to the show. Good luck!
