Aimi Jones had put the dress up for auction after she did not realise the camera caught her via a mirror wearing nothing but a black bra.
She admitted to The Sun: "It's so embarrassing. It is such a stupid thing to do and now the whole world's seen me in the nude."
Jones quickly took the listing down and replaced it with another - this time with a photo where she was properly clothed.
"As seen by thousands," she jokily posted. "Never worn naked."
The dress then received bids of more than £153,000.
