DEDICATED followers of fashion will have a field day when Hollywood's movie kings and queens come to town. In the three short years since the original restaurant opened to the likes of Kim Basinger, Glenn Close, Don Johnson and Elton John, their styles have ranged from ultra-glamorous to grunge. At Planet Hollywood, it seems anything goes. Jacqueline Bisset wowed the London crowd in a Giorgio Armani trouser suit keeping strictly to classic lines. The outfit cost in the region of $21,500. Sylvester Stallones 'ex', Jennifer Flavin, at that time still with the Hollywood hunk, looked stunning in a figure-hugging black silk crepe number revealing lots of leggy sex appeal. Paula Yates, wife of Bob Geldof, turned up at the London opening in a Vivienne Westwood floral dress and flower-adorned hat. Demi Moore and Bruce Willis chose to display the best of both worlds. He wore low-key baseball gear and she swept in wearing a show-stopping Jean Paul Gaultier suit. So, what can Hong Kong expect to see? With the territory's image as an up-beat, designer-conscious city where socialites and celebrities live and breathe labels, the difference in style between the local tai tais and out-of-towners will be interesting to observe.
