You will need a MANUAL proxy since there are no working Greek web proxies. Sorry. 62.103.162.171 port 8080 worked fast for me.
( Learn how to use a manual proxy HERE )
(if it is slow for you use my trick: wait for the page to start to load (turn white), turn off the proxy, highlight the URL and tap your 'enter' key)
Paste this link into the URL box:
http://www.stardoll.com/en/contest/view.php?id=855
Log in, then paste this link into the box
http://www.stardoll.com/en/contest/finish.php?id=855
Log off the proxy and go to regular Stardoll.
They will be in a bag in your Beauty Parlor.
This contest may still be available:
