Princess Diana's red "black sheep" sweater has set a new world auction record for any article of clothing worn by the late royal.

The sweater sold for $1.1 million at Sotheby’s inaugural Fashion Icons auction on Thursday, becoming the most valuable sweater ever sold at an auction. Diana's garment was estimated to sell for $80,000.

Cynthia Houlton, Sotheby's global head of fashion and accessories, commented on the price of the sale.

"These striking garments and accessories belonging to and worn by some of the most celebrated individuals across the worlds of fashion, film, music and politics each possess a unique narrative in the wide-spanning history of fashion," she began.

"Sotheby's is immensely privileged to showcase these treasures to the world, catering to the passions and enthusiasm of fashion aficionados and collectors alike," Houlton concluded.

In June 1981, the newly engaged Diana donned the red sweater at one of Prince Charles' summer polo matches. The sweater has several white sheep on it with just one black sheep. It was created by Sally Muir and Joanna Osborne and their knitwear label Warm & Wonderful.

"Much to our amazement, the first we knew of Lady Diana Spencer wearing the sweater was when we saw her on the front page of one of the Sunday newspapers. Her influence was impactful almost immediately thereafter, leading to a surge in sales and public awareness of our small label, for which we will be forever grateful," Muir and Osborne shared with the auction.

The sweater was rediscovered this year in the attic of English knitwear shop Warm & Wonderful after the sweater, which had been torn by Diana on the sleeve, was put away in a box decades ago and a replacement was knitted for the royal.

"Apparently, when the letter came from the palace requesting a new one, they said either a repair or a replacement," Frank Everett, Sotheby’s senior VP and sales director for jewelry, previously revealed to the "Today show." "They decided to knit her a new one, and there are some design differences in the second one she wore, and someone just threw it [the first sweater] in a box, and it went in the attic. Forty years later, now here it is at Sotheby’s."

Diana wore the replacement sweater in 1983.

Given the timing of when Diana first sported the bold sweater, it quickly became an international spectacle. People around the world began chiming in on whether the garment choice had a deeper meaning since she first sported it four months after her engagement to Charles and was facing scrutiny from the media.

Sotheby held the previous record for the most valuable piece of clothing Diana owned. In January, the late princess' "Infanta" Style Ball Gown, designed by Victor Edelstein, sold for $604,800. It was estimated to sell for between $80,000 and $120,000.

That same month, Sotheby's sold the amethyst and diamond "Attallah Cross," which was worn by Diana on several different occasions, to Kim Kardashian for $197,453.

Princess Diana died after a car crash in August 1997 in Paris. Her sons, Prince William and Prince Harry, attended the funeral service alongside their father, now King Charles.
