Check it out Wander into the Yue Hwa Chinese Products Emporium and you never know what you might find. A recent visit yielded this old-stock jacket - a cool combination of Comme des Garcons-style checks and a mandarin collar. Discounted to $650 from the chain's flaghip store in Nathan Road, Jordan, it is available in blue and white, as well as a brown-and-beige check that looks a lot like Louis Vuitton's Damier ... Tot shop Martial-arts ensembles, military chic, the preppy look, lots of black ... this season's key trends are now available for style-starved children at the first freestanding DKNY Kids store. Located in Causeway Bay's Caroline Centre - a mecca for designer childrenswear - the shop stocks the popular Kids and Baby lines, which are extensions of the adult collections at a fraction of the price (from $50 to $690). Tower power Few can afford Jean Paul Gaultier couture, but if you save up for a week you'll be able to splash out on his limited-edition, Eiffel Tower stocking, which stole the show at his couture presentation two seasons ago. Manufactured by Wolford, the toe- and heel-less tights cost $730 from Wolford boutiques. A mock-turtleneck body suit with the same design is also available for $1,460. The town's jewels In the market for a flawless, 12.44 carat, pear-shaped, D-colour diamond by Harry Winston? Then take your chequebook to Christie's spring jewellery, jadeite and watches auctions tomorrow and Tuesday at the J.W. Marriott Hotel in Admiralty, where the stone is expected to fetch about $4 million. Other highlights include a number of Winston pieces, a beautiful jadeite-bead necklace (estimated at $8 million to $10 million), and a rare Patek Philippe 18K perpetual calendar and split-second chronograph - a steal starting at $500,000. Less expensive are the limited-edition pens by Montblanc, including a tribute to Leonard Bernstein (only 10 were made) and a porcelain salute to the Year of the Dragon. Book smart It isn't easy being an international jetsetter - getting into all the right restaurants, staying at the latest boutique hotels, knowing where to shop and what to visit in random cities around the world. Which is why stylish travellers swear by Louis Vuitton's City Guides while in Europe. The eight-volume, 32-destination set has just been updated for 2001, with listings for five new cities (Bordeaux, Florence, Porto, St Petersburg and Zurich) and one volume dedicated exclusively to Paris. Don't leave home without it. $460 from Louis Vuitton boutiques.
