46 photos that show how Kaley Cuoco's style has evolved through the years

It's dark for a holiday party.

This really is the beginning of Kaley Cuoco's style roller coaster.

Von Dutch hats were an iconic look in the early 2000s.

This was her first major red carpet event, and she dressed to impress.

She paired it all with a Dior bag.

The actress had recently been cast as Penny on "The Big Bang Theory."

This tribal print is very late 2000s appropriate.

Cuoco looked radiant in this David Meister gown.

As "The Big Bang Theory" became more successful, Cuoco began dressing like the TV A-lister she is. Here, she wears a slinky black Nicole Miller gown.

She presented the "Greatest Hits Award" to Alan Jackson.

Strapless dresses became a favorite for the actress.

This lace Katherine Kidd dress certainly made a statement.

She added a bright pink lip for a pop of color.

Her red pumps and clutch complement this Romona Keveza gown nicely.

Her hair reminds us of the famous "Rachel" hairstyle Jennifer Aniston used to rock in the beginning of "Friends."

The pale turquoise gown stood out on the red carpet.

She also took home an award for favorite comedy series with her "The Big Bang Theory" family.

Cuoco also experimented with a dark lip for the red carpet.

Her (fake) bangs were actually covering up a bruise and stitches that she got on set, but this look received a lot of hate and she even claims that the hair-do almost ruined her career.

This rock-'n'-roll inspired gown is by BCBG Max Azria.

We love the boning and subtle texture of this Vera Wang gown, and the deep red color.

She took home the award for Favorite Comedy TV Actress and another one for Favorite Comedy Series.

This dress looks like a piece of Renaissance art.

This mermaid-style was becoming more and more popular on the red carpet.

Cuoco was a few years early on the red and pink trend we saw on the Emmys red carpet in 2019.

Cuoco is channeling what appears to be a Barbie Flight Attendant — perhaps foreshadowing her latest role?

This KaufmanFranco dress is a departure from her normal look.

This geometric two-piece set was an even bigger change. The "Big Bang Theory" star was clearly starting to feel more comfortable taking risks.

The strapless Romona Keveza shift dress brought out Cuoco's tan, but she really could've used a necklace.

Perhaps Cuoco should stick to simpler dresses in the future — she looks absolutely radiant in this one.

Cuoco wore a killer top knot with her look from the Romona Keveza Collection.

This sequined look landed her on the best dressed list.

This look doesn't totally work, but we respect for her trying something different.

This deep-V gown is by Tommy Hilfiger.

It's an ethereal look.

She wore the blouse unbuttoned.

This gown also has a sheer element, something that Cuoco has returned to frequently as of late.

This J. Mendel dress proves why Cuoco gravitates towards pale pink so often — she glows.

She'll return to this silhouette in the future.

She paired the dress with sneakers for a more casual look.

Bonus: It has pockets.

It was a regal look.

She and the rest of the cast of "The Big Bang Theory" pressed their handprints into cement that day.

Cuoco is just one of many celebs in to embrace the no-shirt trend.

She rocked a slicked-back ponytail with this look.

As Cuoco has grown in her career, her style has grown, too.
