London, June 7 (IANS) A bold black gown worn by the late Princess Diana when she was 19 will go under the hammer Tuesday.

The dress became a sensation when photographed back in 1981 and is expected to fetch around $72,000 at the auction, reports dailystar.co.uk.

‘The British public hadn’t seen a potential royal (Princess Diana) who was young and sexy,’ said auctioneer Kerry Taylor of London’s Pall Mall.
