Kaley Cuoco landed her breakout role on the sitcom “8 Simple Rules.” Two years later, she snagged a lead role on “The Big Bang Theory,” which wrapped up in 2019 after 12 seasons.

Kaley Cuoco wore a scrunched midriff shirt, wide black pants, and this black coat with obnoxiously long sleeves to a 2002 holiday party.

In 2003, Cuoco arrived at the Solstice Fashion Party in an interesting up-do and an even more interesting ensemble.

She rounded out the year at the film premiere of “Jeepers Creepers 2” where she wore ripped flare jeans and a Von Dutch trucker hat.

Cuoco kicked off 2004 in a light pink gown at the People’s Choice Awards.

She wore this tied-up “Love Brad” shirt to a Glamour party in 2004.

Flash forward four years to Cuoco’s little black dress at the 2008 Academy of Country Music Awards.

At the 2009 Emmy Awards, the actress rocked a glistening sequin halter gown that matched her golden locks.

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