What Princess Diana wore before she became a royal

Well, isn't she cute? Showing her love of red from an early age, we might never get over how adorable this puffer coat is.

Here's a sweet primary school pic of Diana, wearing a (very patriotic) red, white and blue look with a matching headband.

This snap of Diana sporting a wide-brimmed hat, taken on a family holiday to West Sussex, is a testament to the future royal's enduring love of fashion.

Growing up on her family's Althorp Estate, Diana had low-key, country attire down from an early age. Look here at her powder blue sweater paired with indigo wash jeans, worn by the youngster as she was photographed with her pet pony, Soufflé.

Layering a vibrant shirt underneath a buttoned-up cardigan feels like the kind of thing that shouldn't really work, but it totally does. Especially when finished with a string of pearls around the neck, à la Diana.

Of course, no wrap-up of Diana's pre-royal style would be complete without a nod to her iconic sheep jumper, worn with a pair of jeans to watch Prince Charles at the polo. In fact, this jumper's become so famous, UK brand Rowing Blazers brought it back last year along with the Princess' famous 'I'm a luxury' knit.

Leaving the Young England kindergarten in Pimlico, this pleated skirt and jumper look, with each of the sleeves pushed up, is what the future Princess wore when she worked as a teacher.

Do our eyes deceive us, or is Diana wearing lime green tights to match her preppy V-neck jumper? It really looks like it, and we're loving such an edgy style move from the soon-to-be-royal, who completed the look with a woven basket and checked skirt.

Diana wore this polished ruby red blazer and black ensemble around Earl's Court prior to her engagement to Charles.

Putting her own spin on the dungarees trend, Di wore this lemon yellow iteration over a technicolour collared blouse for a trip to the polo. Extra style points for the statement wedges (perfect for walking across the lawns) and the oversized shades perched atop of her head. If you think it looks familiar, it was one of the many Diana looks recreated in The Crown.

Here's Diana leaving her flat at Earl's Court wearing a navy pinstripe skirt and an oxblood cardigan (with matching accessories) over a high-collar shirt, all tied together with a contrasting black bow.

Can anyone else imagine Diana as Miss Honey from Matilda in this midi dress, as she arrives for work at the Young England School kindergarten? The only thing missing is the iconic glasses, which would subsequently be pushed down her nose in astonishment.

Diana was a big fan of cornflower blue, as demonstrated by this monotone look, and who can blame her? She wears it so well.

The way the future princess effortlessly drapes this jumper over her shoulders is just so chic.

This snap of Diana was taken as she left the Ritz Hotel after attending Princess Margaret's 50th birthday party, when rumours first started circulating of her romance with Charles. You can see a blush pink ballgown with pinstripe details poking out from underneath her black overcoat and, wow, do we wish we could see the whole thing!

Di's royal blue skirt suit, worn for the announcement of her engagement to Prince Charles, famously matched her sapphire engagement ring. Our favourite detail, though? The polished pussybow blouse, tied to the side.

Looking every bit the country lass, Diana wore a colourful knit, oversized trousers and forest green Wellington boots for a trip to Balmoral with Prince Charles prior to their wedding.

Anyone who's seen The Crown will remember this strapless black dress is what Diana wore for her first official public engagement with Charles. Notably, it was the gown's revealing neckline that caused a stir as a marked shift from the family's more conservative dress code.

Spaghetti straps aren't something we tend to associate with royals but before she was officially Princess of Wales, Diana wore this stunning cherry red dress with a matching ruby necklace for the premiere of For Your Eyes Only in Leicester Square.

Here's one of Di's first Royal Ascot outfits - a gloriously '80s peach number, with a frilly ivory collar, long gloves and an ornate hat.
