Christian Dior will unveil its Davis bag tomorrow at its St George's Building boutique. The event, for the fashion press, will come after a trunk show for customers showcasing the new season's lavish wearables. The Davis bag is largely expected to take off on the success of the best-selling Cannage bag, which rose to fame when Princess Diana started carrying it. For information, call 2968-9626. Chanel show With its new philosophy, 'Let Chanel Surprise You', the venerated French couture, ready-to-wear and accessories house puts its money where its motto is by holding a fashion show on Friday at the hip and modern ARTSPACE gallery in Aberdeen. The gallery was chosen by Chanel as the perfect backdrop to the season's neo-modern (simple yet luxurious) fashion. The company will provide transport from Causeway Bay. Details, call 2826-7624. Previews The Italian Trade Commission is already looking ahead to next spring, and will preview a spring/summer 1999 collection of men's and women's clothes next week. The upcoming label, Ecce, will be shown as part of a 'Made in Italy' event next Tuesday evening at the Mandarin Oriental Hotel. For non-fashion fans, a selection of food and wine is also showcased.

Retailers are advising customers not to be deterred by the sumptuous cashmere coats and heavy sweaters in windows: for cross-climatic dressing, there are plenty of lightweight cap-sleeved tops, sweet pleated skirts and easy wide-legged pants.
