Buying underwear is such an intimate thing that most of us prefer doing either alone of with the closest friends or relatives, possibly partners. Perhaps that's why it's even less comfortable when a shop assistant comes to you and kindly offers some help which means "tell me your size / shape / everything you're proud of and not only, I promise not to tell anyone". But this shop assistant is going to surprise you in a totally different way, that's for sure! Enjoy!
