Anna Wintour’s crush on Roger Federer extends to sending him expensive clothes, reports “Page Six.” (The Post gossip column also coins the phrase “comely cougar” to describe the steely Vogue editor, which is just so catty and, you know, accurate.) But a Condé Nast rep protests, “Vogue certainly helps a number of people with fashion, but Roger’s style is all his own.” We have to beg to differ on this one. The fashion bible has repeatedly featured Federer, dressing him up in all kinds of outrageously luxe clothes. In one Men’s Vogue spread alone (shot by Annie Leibovitz), Wintour draped Federer in over $4,000 worth of Prada, $2,500 worth of Gucci, $1,500 worth of Dolce & Gabbana and Michael Kors, and $2,500 worth of Dior Homme. Since much of that shoot took place at sea or on the beach, it wouldn’t be outrageous if some of the clothes didn’t get returned to the designers. Not that we object — handsome men deserve to wear expensive clothes. We’re just wondering whether Wintour has taken to calling Federer “my pretty” yet.
