Princess Diana's Iconic Sweaters Head to Auction Block

Princess Diana's iconic "black sheep" sweater, which she wore in 1981 and became known as a fashion icon, is going up for auction at Sotheby's and is expected to sell for $50,000 to $80,000. The red sweater with white sheep – and one black sheep – was from the knitwear line Warm & Wonderful and helped further the fashion brand. Diana's sweater became one of her most recognizable clothing pieces and a replica was included in "The Crown," the Netflix series about the royals.
