Never is a hemline too short, or too flyaway, Never is a hair in her remarkable bouffant out of place. Styles that would look anachronistic on anyone else just seem to work on Anne (maybe thanks, in part, to the fact that her hairstyle remains locked into 1963). And so to Cowes today, where the annual regatta kicked off on the weekend. Princess Anne arrived this morning in typically elegant attire, looking as though she had just stepped off the pages of a Sperry catalogue. Scroll down for video . Sailing in: A double-breasted blazer, navy of course, white trousers and brown deck shoes made up Anne's Cowes uniform . Dreamboat! Anne has yachting style nailed in her double-breasted blazer and sensible deck shoes . The formula - and any virgin Regatta attendees should take note - is a navy blazer, double-breasted style a must, gold buttons advisable. Cotton chino-style trousers, preferably white. Navy and beige also acceptable, as are red or pink for gentlemen. Shoes, as Anne demonstrates, should be a flat, deck shoe style. For Anne, something sensible and brown fits the bill; others could make a splash with a pair of Sebago docksides (as worn by the Duchess of Cambridge on a boating outing last year), or Sperry, an American company who have been making boat shoes since 1935.
