Kaley Cuoco-Sweeting isn't afraid to take risks—especially on the red carpet.
The Big Bang Theory actress is known for her unique style, which usually consists of attention-grabbing colors.
Take her yellow Angel Sanchez dress at the 2012 Emmy Awards or her refreshing mint ball gown at the 2013 SAG Awards.
It should be noted that the star is also a pro at pulling off the little black dress. At the 2011 Emmys, she rocked a lovely Romona Keveza number, and two years later, stunned in a sequin LBD by Monique Lhuillier at the Academy of Television Arts & Sciences Hall of Fame induction ceremony.
Take a look back at Kaley's best red carpet looks, before she wows us again at Sunday's 2013 Emmys.
