If you are from Norway just log into stardoll and click HERE. If you are from anywhere else you will need to use a manual proxy. Set your manual proxy to 18.104.22.168 port 8080 (thanks BIS)
Find out how to set manual proxy here
Log into stardoll then go to http://hairtops.blogspot.com/en/contest/finish.php?id=1374
Once the page has loaded remove the manual proxy. The swimsuit should be in a starplaza bag in your suite.
