On St Barts' beaches, they coo, the girls change into Dior thongs to get that all-over Playboy tan, sans top, naturally, the billionaires' yachts are so big they carry choppers (Revlon boss Ron Perelman and wife Hollywood actress Ellen Barkin's monstrous wedding cake of a gin palace, Ultima Three, was displacing half the harbour the day I was there) and the boutiques in Gustavia, a baby Champs Elysées, are so chic they close when the cruise ships dock because who in Hermes, Gucci and Yves St Laurent wants cruise passengers fingering all those yummy tops and towels? Puts off the real money, heart face, the ones with the American Express black plastic.
