Hairdresser Jo shed three stone last year, and she was desperate to flaunt her new figure as she partied with friends at London hotspot DSTRKT.

But she almost ended up in her birthday suitas she climbed into a cab at the end of the night - coming within millimetres of a nip slip as the top of the her frock fell open and her breasts almost tumbled out.
