I was 17 at the time and I went into town with my boyfriend. I was wearing a white cotton halterneck dress with only a pair of panties on underneath.

Anyway, we took a taxi into town and I sat in the seat in front of my boyfriend, next to the taxi driver. My boyfriend somehow managed to reach up behind me and gentle pull the string on my halterneck. You know how easy they are to undo.. i didn't even notice he'd done it until I stood up. I jumped out of the car onto a busy pavement as soon as the taxi stopped and the whole dress just slipped down to the ground and I was left standing there in just my thong! People were looking and laughing at me, i was so embarrassed I could've died! It was really busy and I was almost completely naked it was awful, I wasn't even wearing a bra. I sat back down in the passenger seat as quick as possible to hide myself but the taxi driver could see and people could see me through the car window. Even worse - I was really shocked so didn't react as quickly as my boyfriend who reached down and picked up the dress before I could so I was sitting in the passenger seat of a taxi, really exposed, trying to get my boyfriend to give my clothes back. He did give them back but I still have to think of a good way to take revenge on him. I was blushing so much and still cringe when I think about my moment of nudity in public.
