If you've been planning on flashing the plastic on, now is the time to do it. If you shop with a Mastercard on the site today and use the code 'fashionrocks' at the checkout, you'll be entered into a draw to win tickets to the Swarovski Fashion Rocks event in London on Thursday, complete with accommodation and travel to and from the venue. Between 15th and 29th October, Mastercard shoppers can also benefit from a 15% discount on the site, meaning a decent saving on designer items like this £171 Sara Berman blouse and the £412 sequinned See by Chloe dress we used in our 'Glitter & Twisted' fashion shoot.
