And according to reports, they didn’t always see eye to eye.

Sophie, meanwhile, married a lower-ranking Mountbatten-Windsor.

As a result, Sophie is not exactly a household name.

The differences between the two women multiply from there.

All we know for sure is that Charles met Diana when she was only a teen.

While Diana is rumored to have submitted to the check, perExpress, Sophie didn’t have to.

This didn’t stopThe Los Angeles Timesfrom dubbing Sophie “Di-dentical” to her future sister-in-law.

Diana reportedly didn’t attempt to make Sophie feel better behind closed doors, either.

At a family gathering, Diana allegedly stared intensely at Sophie during teatime with the royal family.

Sophie reportedly left the encounter in tears.

Her short blond hair was especially influential.

Sophie, Duchess of Edinburgh, was seemingly one of those women.

Tall with short blond hair, Sophie couldn’t have been surprised when the comparisons came flooding in.

Diana also thought the then-royal-girlfriend was copying other aspects of her lifestyle.

Diana was known for her tailored, streamlined ’90s looks and she thought Sophie was mimicking them.

“She really ought to get her own look,” Wade recounted Diana as saying.

“And there are plenty of things she could do.

She could dress in softer, less tailored clothes, just to find her own look.”

Not even Sophie’s fitness routine was safe from Diana’s ire.

Diana famously worked out at the chic Harbour Club in Chelsea, according toThe Evening Standard.

But Diana reportedly took Sophie’s membership there as yet another attempt at copying.

Do royal women copy each other’s outfits due to a lack of creativity or a lack of options?

It’s an eternal debate.

In the royal family, high-value jewels are often gifted to the reigning monarch.

The monarch can lend them out to the other royal women.

That’s how Diana came to wear the showstopping King Faisal diamond necklace in 1983.

It was a gift from King Faisal of Saudi Arabia to Queen Elizabeth II.

Sophie, Duchess of Edinburgh, received totally different treatment, according to some reports.

And this may have contributed to Diana’s disdain for Sophie.

Meanwhile, Diana called Prince Charles “sir” until they were engaged.

Whether that was required by the family or not is unclear.

Diana had no such experience.

As Sophie took it slow, she received rave reviews from the royal family and the public alike.

OneExpressheadline trumpeted that Sophie “excelled in royal life where … Diana failed.”

We were thrown to the wolves.”

Diana died in 1997 and wasn’t around for the “Fake Sheikh” dust-up.
