We've just spent an afternoon getting a little bit addicted to Retail Therapy, a Facebook app that allows you to own your own store, shop in your friends' stores and even take a trip to Topshop for an online style fix! Once you've added the application to your profile you get to choose your character down to the hair, make-up and outfit and then start filling up your shop with all the goodies on offer.

As people pour in and buy your carefully picked pieces you'll need to restock, just like a real shop! You can decorate, suggest outfits for your friends and even buy puppies to cheer the place up. Plus if you use this link to open your store you'll get double the credits to help start you up. It's every style-setter's dream to own their own boutique, and here's your chance. Being in the retail business has never been so much fun!
