If you want to see where it all started, the Pompadour-punk ball gowns, Lady Hamilton vest coats, and foppish landmark getups are the core of Westwood's first boutique at 430 King's Road, Chelsea SW3. The designer still represents the apex of high-style British couture, and the Davies Street boutique sells the Gold Label line of intoxicatingly glamorous creations: ready-to-wear or made-to-measure. At 44 Conduit Street, Mayfair W1, the story is the sharper Red Line: hot, pared-down catwalk versions; menswear is also offered here -- the Westwood influence is far-reaching. Tube: Bond St.
