Kaley Cuoco has had a big year. In September, Forbes named her the one TV’s highest-paid actresses. A few weeks later, news surfaced that she was splitting from her husband of less than two years, Ryan Sweeting. This month, the actress is set to celebrate her 30th birthday.

And boy, has Cuoco done a lot in 30 years. Though she is most well-known for her role as Penny on the hit sitcom “The Big Bang Theory,” the California native has actually been acting since the mid-nineties. She began her career by making cameos in hit shows like “My-So Called Life” and “7th Heaven,” and was cast as Bridget Hennessy in “8 Simple Rules” in 2002.

In honor of Cuoco’s golden birthday on Nov. 30, we’re taking a look at her style evolution over the years. During the early 2000s she favored midriff-baring tops and low rise jeans, but today, the mega-star sticks to glamorous gowns and tailored suits (okay, and still midriff baring tops. What can we say, the girl loves a crop top!)

Check out Cuoco’s most memorable looks to date.
