Selection from a typical Chassidic wedding invitation:
If you are unacquainted with this phrase, it means "the praise-worthy virgin bride".
I've always found this almost universal custom not only anachronistic (after all, the family is not also parading around the bloody tokens of her deflowering, are they?) but also somewhat offensive. It seems no different from saying (albeit more crudely), "Hey everyone, our wonderful daughter hasn't been shtupped yet!" Yeah, it's implicitly understood, so why do people feel the need to publicize it? (Note also that in these circles it is likely that the chassan is also a virgin, but it isn't so praiseworthy that it needs to be advertised.)
Publicizing their daughter's sexual status - sheesh, haven't these people heard about tznius?
