She's got the best accessory in town, but that's not the only reason George Clooney's girlfriend turns heads on the red carpet.

"I've always loved fashion," Us Weekly Hot Hollywood honoree Stacy Keibler says.

However, the 32-year-old Fixing Pete star didn't hone her sartorial skills overnight.

"I've definitely evolved," she says of trading trendy looks for timeless pieces by Marchesa, Dolce & Gabbana and Michael Kors.

So what does Clooney think of Keibler's wardrobe? "He is always happy with everything that I wear. He doesn't care whether I'm dressed up or down."

In the video above, the actress poses for her glamorous Hot Hollywood photo shoot and talks about what it's like to work with top designers, the pressure to always look put-together and more.
