Gwen Stefani is a gal of many tribes — six, to be exact — as demonstrated to jazzy effect on her L.A.M.B. runway. She split the show into different sections revolving around the label’s signature looks, each with its own video cue by music-video director Sophie Muller. So with helicopters roaring in the background, out came the “Soldier Girls” in military-inspired gear: a mohair plaid tailcoat in shades of army greens, an aviator jacket cut in shearling and a sheer camo blouse and pleated skirt. Then, the “Ragga Muffin Girls,” who worked a rasta-meets-New Mexico vibe in Navajo-print dresses and slouchy coats. Next up were the punkish men’s wear-inspired “London Girls,” heavy on the tartans and attitude. “Buffalo Girls” was a street take on the Wild West (the patchwork wrap coat was great), while “Mod Girls” was, well, Mod with its all black-and-white graphic series. The “Glamour Girls” finale read Bond-girl sexy — slinky draped dresses and gold jewelry by Noir. It was a kicky end to fashion week, though some of the fabrics and construction were lacking. (The platforms broke on two different shoes; in one instance the model went careening into the catwalk.) But kudos to Stefani for selecting one of the season’s most ethnically diverse shows — the various sets featured chic crews of Asian, African and Caucasian faces.
