Wow, what a fantastic stories in this thread. I am always looking for girls with her zipper down and also hoping that co-workers will forget to zip up. But I have no luck at all. The last time I saw a girl with her zipper down in public (on the streets) was in 2019 (before Corona)
It seems that the girls in my country (western Europe) are really carefull about properly closing the zipper, where latin girls (in South America) are more careless about that.
