If you are from England or USA ( I think it will work there)
Just click here.
It will take you to the cinema page, just watch the video (skip to the end if you like) and it will be in your suite.
If you are from other countries and it doesn't work just go to http://www.daveproxy.co.uk
Put this in the url bar and then press go or enter http://www.stardoll.com/en/cinema/?id=155
Wait for the page to load and then log in.
Once that page has loaded just go to your offcial Stardoll suite and it should be there.
It should come in a bag like this:
And the dress should look like this:
Hope it works,
