Free Dress (The Den)!

If you're not from the UK, use one of these proxy servers:
http://www.docoja.com/blue/
http://www.goproxing.com/
http://www.hestudy.info/
http://www.idiotfly.info/

Go to Stardoll.com or Stardoll.com/campaigns/den_uk/contest.php
with the proxy server and log into Stardoll.

Now paste:
http://www.stardoll.com/en/campaigns/den_uk/contest.php?gift=true
into the URL bar of the proxy server and hit enter.
I'll be sent to the official site outside of Stardoll, which is normal.
