This is the place for the career woman who requires quality, cut, and style in a suit, plus weekend wear in summer linens and silks, or winter hand-knit woolens. Prices are on the high side, but there's some affordable wear as well, especially the sporty, casual Diversion label. Farhi offers an equally desirable men's line at 11 Floral Street, Covent Garden WC2. Further outlets for women are also at Unit 15, The Piazza, Covent Garden WC2; 193 Sloane Street, Belgravia SW1; and farther afield at 27 Hampstead High Street, Hampstead NW3. The downstairs in-store restaurant, Nicole's (PHONE: 020/7499-8408), is not just somewhere to resuscitate between purchases: Ms. Farhi designed the space and the menu to her own taste, and it's an extension of the fashion statement, a hot spot for lunching fashionistas who like to be seen. It's wise to reserve ahead. Tube: Bond St.
