Irina Lazareanu is used to juggling job titles. Although she's best known as a model, she's also been a songwriter with beau Pete Doherty and his band, Babyshambles, and a muse to Nicolas Ghesquière at Balenciaga. So it doesn't come as a shock that her Friday was divided between being a fashion week participant and an audience member. She started her day "with about 12 fittings," hopped into the front row at Erin Fetherston, swung by the Sue Stemp presentation at Norwood, and then, to fill her musical desires, visited pal Diego Garcia at Elise Øverland's presentation at Milk Studios. Actually, that was a mix of her musical and muse hats—Øverland asked to meet the trendsetter. "I think she's so stylish," Øverland said of the Doc Martens Lazareanu paired with her Erin Fetherston dress and Burberry trench. "I'd let her take anything out of here now." But being a model, muse, and musician gets tiring. "Let's go to Pop Burger," Lazareanu announced as she left Milk. "I need some carbs."
