For his big date on the hallowed Centre Court the Swiss champion looked sharp in a multi-pocketed jacket, complete with gold trimming and buttons, that could have been straight off the catwalk at this weekend's men's fashion shows in Milan.
On peeling off his jacket he revealed a waistcoat and loose slacks that might have been worn by the gentleman players of yesteryear.
While his outfit was almost the epitome of Wimbledon understatement, his bag boasting an RF crest and natty trainers with a gilded Nike logo, were rather more bling.
"It's kind of a little bit more of a modern look with military, but staying true to Wimbledon with the white," explained Roger, who's now the top seed – meaning he's the favourite to lift the trophy – after injured world number one Rafael Nadal pulled out.
But he wasn't the only one serving up a fashion statement. Maria Sharapova opted for a close-fitting 'majorette' coat over the trendy pair of shorts she sported last year. The Russian star took this off to show a short white dress.
Flamboyant American player Serena Williams can always be relied on for an interesting look as well. True to form on Monday, she'd donned a British Mac, which stayed on despite the warm weather.
In 2008, the younger Williams sister delighted fans with a Nike-designed American belted trenchcoat, but this year it was her wish to go "all English".
