The 30-year-old model said she steals items from her actor husband's wardrobe as she covets his relaxed rock 'n' roll style, reported Contactmusic.
"Sometimes I wear my husband's jacket or T-shirt. It feels good because it's his and it's fun to mix it up," Kerr said.
Kerr, who is known for her sexy and sophisticated style, believes that one cannot go wrong with classic pieces.
"A great pair of jeans or a cool blazer. I also like a high waisted skirt... It's really important to find out what works for you as an individual, so find pieces that you know flatter your body shaped. That's what I try to do. Experimenting with fashion is fun," she said.
"I exercise every day-be it yoga, hiking, pilates or resistance training. I've been practising yoga for over 10 years and my son often holds on to me like a koala! Flynn loves to dance, so I dance with him, too," she added.
