I used Random.org to pick a winner for my contest giveaway and the winner is commenter number 10; Rachinald. Congratulations! I will email you and pass your details onto Shopbop, so that they can send you your gift certificate.
Also, I was browsing the "new this week" section on the Topshop website, and I love this dinosaur sweater! I think I may have to treat myself. Geeky, educational sweaters are the way forward ;)!
