Proof That No One Did Sweater Weather Better Than Princess Diana

Princess Diana's black sheep sweater, which she wore to two polo matches in the 1980s, sent a clear message of how she felt as part of the royal family. (And now the sweater is making a comeback for the new generation!)

Before Diana married Prince Charles, sweaters (like this purple sweater vest) were a part of her wardrobe as a kindergarten assistant.

Ahead of their royal wedding, Princess Diana posed for a photo with Prince Charles at Balmoral wearing a pink patterned pullover with trousers and boots.

Princess Diana cozied up in fun sweaters, like this jumper depicting a koala, while pregnant.

The royal mom put her own spin on a white turtleneck sweater by cinching it at the waist.

The royal wrapped up in a white cardigan sans buttons over a pink dress for a 1984 polo match.

Princess Diana had the perfect practical accessory at a polo game in 1985, casually tying a red sweater (which complemented her floral pants and matched her shoes) over her shoulders.

During a school run for son Prince William, Diana opted for a blue patterned pullover that she cinched at the waist with a wide belt.

Sweaters were a key piece of Diana's mom wardrobe, like this red cardigan she wore while doing a puzzle at home with William.

For some outdoor play time with a young Prince Harry, Diana wore a pink knit over a white shirt and gingham pants.

Princess Diana's polo sweater was the perfect cover-up for a plane ride with her two sons.

For a family portrait (including a cute pup!), Diana coordinated her blue skirt with an oversized cardigan.

For Prince Harry's first day of school, she wore a red skirt and coordinating knit.

Diana chose a navy cardigan with horizontal white stripes for a school run in 1989.

Princess Diana had a laugh with sons William and Harry during a ski holiday, riding in a sleigh wearing a pink V-neck sweater over a white turtleneck.
