Christina Aguilerais a style chameleon.

And she is every bit as adept at switching things up as the original “Material Girl.”

This ability has been on display since the start of her career.

She was clearly a star on the rise and a style icon in the making.

Her image sharpened by the time she notched her third No.

InStylenoted that the trends Aguilera helped popularize in the early millennium are very much back in fashion today.

So many of her looks from the era remain relevant.

However, one her “dirrtiest,” if you will exists in a class above the rest.

A lot had changed for the hitmaker since “Genie In A Bottle” made her a household name.

In 2000, she dropped a Spanish-language album and a Christmas album.

Those projects helped her develop a creative range that set her apart from peers likeBritney Spears.

“And I wasn’t about to play that game, I wasn’t that girl.

I really wanted to be honest and truthful.

So I came out with Dirrty.

That was me stepping up and saying I was a woman that’s proud of my sexuality.

I was proud of my vulnerability.

I was proud of the fact that I’ve fought my way through this industry.”

That brash rebelliousness was on full display in the David LaChapelle-directed music video (viaYouTube).

Although it was the first time she wore the chaps, it would not be the last.

Not by a long shot.

Aguilera recycled the look for a 2002 performance on MTV.

This time, she took the stage wearing a yellow-and-black-striped pair of chaps and a matching bikini top.

This set was emblazoned with her nickname Xtina (via YouTube).

And they just kept popping up.

There’s no denying it: The chaps were athing.

Her big sisterKim Kardashiansparked comparisons when she wore a similar look in 2020 (viaInStyle).

She took toTwitterto compliment Cyrus as a fellow “dirrty girl.”

Aguilera wrote: “Wear em' loud & proud, girl.”

Of course, it doesn’t hurt that Aguilera plays up the look’s legacy.

And her wardrobe for the song’s music video clearly holds a special place in her heart.

The diva hilariously gifted a pair to Andy Cohen’s newborn son in 2019 (viaPeople).

She still wears them herself, too.

She even took them out of retirement when she performed at the Hollywood Bowl in 2021.

How did Ottenberg bring the look into 2021?

By introducing the concept of tuxedo chaps with a bedazzled thong.

“This whole getup really brought the house down.

This is one of my favorite stage outfits I’ve ever done, for sure,” Ottenberg gushed.

“And I bet it’s one of Christina’s favorites now, too.”
