READ THIS: Please make sure you have at least one published Starmovie before you go ahead reading this.
If you are from Finland, log in to Stardoll, click HERE, select one of your Starmovies and click 'Enter competition'. The necklace should be in your Beauty Parlor.
If you are from anywhere else, you'll have to use a manual proxy (How? Click HERE).
Web proxies don't work with this kind of contests.

This one worked for me:
IP: 82.130.33.68    Port: 3128
OR click HERE for more.

After setting the manual proxy, go to this link:

http://www.stardoll.com/en/contest/view.php?id=2645

Hit Enter and log in to your account. Once you log in, select a Starmovie and click 'Enter competition'. You can now get rid of the manual proxy. The necklace should be in your Beauty Parlor.

ATTENTION: Even though these are not web proxies with ads, we can not ensure that you will be safe. I've been using manual proxies for some time and nothing ever happened to my account. These proxies are third party proxies, open for public use.
