Anne did stick to the “something borrowed” tradition, too.

The dark green gown she wore to the Society of Film and Television Awards in 1971 was no exception.

And, luckily for us, we got this incredible fashion moment to commemorate the occasion.

Often spotted in the rider-chic looks that would make Ralph Lauren proud, Anne shone on horseback.

In 1971, the Princess Royal dazzled in the European Eventing Championships, delivering a show-stopping dressage performance.

The 19-year-old princess sported a canary yellow coat dress and matching hat.

She has been for her entire life thus far one of the most steadfast members of the royal family.

She wore theMeander Tiara, which fits more like a headband than a crown.

The tiara was originally given to Queen Elizabeth II by Philip’s mother and was later gifted to Anne.

It has since been seen worn by Anne’s daughter,Zara Phillips, on her wedding day.

Altogether, the elements of the coat dress flattered the princess beautifully.

Topping off this iconic look were a few key elements that just scream “Princess Anne.”

The princess opted for a pill-box hat, which was very circa 1950s (think Jackie Kennedy).

Honestly, this is a look that deserves to be in Vogue.

Anne has been seen in trousers not only in casual tweaks but in professional appearances as well.

Anne wore her royal blue military uniform slacks included alongside her brothers.

When it comes to feminist icons, Anne should certainly be on the list.

All lined up, they look like the Powerpuff Girls … but in the best way possible.

Fashion is about bold colors, big hair, and intricate patterns.

Princess Anne embraced the trends of the time while on a royal trip to Africa.

This look was a departure from the princess' usual style.

She predominantly wore more gender-neutral outfits.

Embracing her more feminine side, Anne completed this iconic look with teased hair.

The late queen often wore bright green, including on her90th birthdayin 2016.

She was said to wearsuch bright colorsso that members of the public could spot her in the crowd.

The queen, meanwhile, was photographed wearing gasp black and white!

That remains true, but there is one look that deserves its own attention.

If the ’70s were an outfit, this would be it.

Anne and Phillips were quickly whisked away to their car.
