She designs her own clothing line, but Whitney Port isn’t making any extra room in her closet these days. The former “City” is on a “shopping strike.” “I just moved into a new place and organized my closet, and I realized that I really shouldn’t buy anything else, I literally have stuff with tags still attached, so I’m just going to revamp my existing pieces for fall,” she says. That includes menswear, “I love a pantsuit,” she shares, plus kitten heels. Port was on hand at Domaine Chandon in Napa Valley, Calif., last week to present the spring 2012 Whitney Eve show and benefit the National Breast Cancer Foundation during an “Eve of Hope.” “I have family members that have been affected by the disease, and I really want to stress the importance of early detection,” the starlet shares. “It’s so crucial to go out and get tested, because the earlier they find something, the better chances you have of survival.” Port’s spring 2012 collection includes tops, skirts, dresses and blazers with stripes, swirls of color and delicate details. “I mostly design what I want to wear myself,” Port explains. “I try to focus on easy pieces, printed rompers, organic jersey dresses and slouchy tees. I really stand by my designs … I poured my heart into this collection.”
