They are Irish Travellers. She was 15 and he was 17. The lady with her bra almost over her dress is the girls mother and the man on the other side is her father. They were in an episode of My Big Fat Gypsy Wedding. In spite of dressing like tarts, these people are strict Orthodox Catholic, the girls are not allowed to go out with boys unaccompanied by a chaperone, and preferably not at all. They are all virgins when they marry and marriage is for life. Some of them have only met their grooms twice before their wedding day. A very strict life.
