Aw man, and I was listening to something else at the time.
I will answer then, if a girl has the ribbon belt tied to her left she is single, if tied to the right she is married. That part is about 40 seconds in, but of course you have to speak German to understand that, and she speaks quite fast. :)
She is/was single when she made this video, in 2012. But young ladies like this, are never really single are they?
