It may be a diffusion collection, but Vivienne Westwood Red Label must be a red-hot seller if the gargantuan venue she chose to show her latest collection is anything to go by. The show took place at Earls Court Exhibition Centre, the same locale where Giorgio Armani staged his grand-scale “One Night Only” show and party exactly two years ago. On Thursday night, the doyenne of British fashion sent a troop of Bedouin-style babes down a slick black runway against a backdrop of a rising red sun. Westwood incorporated elements of men’s tailoring in light wool fabrics into the collection, alongside fresh shirtdresses in stripped or checked cotton, some with Arabian hoods. Gold lamé was worked into cropped biker jackets and harem pants, while shiny metallic stretch fabric made for slinky fitted dresses. Prints reminiscent of Kilim carpets appeared in knitwear. All in all, the collection was easy and wearable.
