The famous red lambswool sweater worn by Princess Diana in 1981, shortly after her engagement to Prince Charles, sold for $1.1 million today, Sotheby’s said, after a fierce “battle” of bidding through of the Internet.

The buyer’s bid, including taxes and commission, is more than ten times Sotheby’s original estimate: the auction house estimated it would fetch between $50,000 and $80,000.

The auction started on August 31, but in the last few hours the “hits” followed each other and the price jumped from 200,000 to 1.1 million.

Immediately after her engagement, Diana Spencer appeared in June 1981 in this red sweater with white lambs – except for one black one – at a polo match, attended by then-Prince Charles.

The princess made a sensation with her comfortable, relaxed demeanor but at the same time she also made famous the designers of the clothes, Sally Muir and Joanna Osborne who had founded the company Warm & Wonderful.

A few weeks later, they received a letter from Buckingham Palace explaining that the future Princess of Wales had accidentally torn the sweater and asking if it could be repaired or replaced.

The two women knitted a new sweater, which Diana wore in 1983, but the one sold today was the original.
