On what she likes:
"I truly, genuinely like clothes. Making them is an art form, and wearing them is a form of self-expression. I find it very emotional because I can remember moments in my life--my mood, how I felt--through these clothes."
Her biggest purchase:
"The biggest fashion purchase I ever made I thought about for six years. I'm not kidding. All my life I wanted to own an Hermès Constance bag, and when I signed with Calvin Klein, I decided this was the time that I could afford it. I truly broke a sweat when I paid for it."
Oh, to live Diane's life! (Here's an Hermès bag we can afford.)And does boyfriend Joshua Jackson share her love of style?
On what her favorite look is:
"We go shopping. But he likes it. I definitely wasn't fond of these blue sneakers that he wore all the time for about a year and a half."
"A well-cut dress. It's all about the cut. I love three-quarter sleeves. I definitely like it classic; less is more. The thing I despise most is vulgarity, and there's a lot of that here [in L.A.]."
