If you join this club you get a free purple shirt with a black vest.
All you have to do is:
1. Use this proxy:http://surfaanonymt se/
2. Type http://www.stardoll.com/sv/clubs/home.php?id=1407858 in the Http:// bar
3. Log in and then you'll be taken to the club.
4. Click on the thing that says nvite 5 friends. It will be in Scandanvian but you'll see a bar with your friends name on it.
5. Invite 5 frends and when they join you'll get a purple shirt with a black vest.
Note: This will not work for everyone, it did not work for me or Helgahufflepuff (the girl that told me this cheat) but it's worth a try.
