Say what you will about Mark Ronson -- and let's face it, there's something faintly infuriating about the Winehouse-enabling, Smiths-butchering, celeb-family-having superstar DJ -- the man knows his way around the men's department. Despite his fashion-party ubiquity and scenester tendencies, Ronson keeps it pretty consistent with his wardrobe: shiny suits and skinny ties onstage, cutting-edge casual wear off it, all pulled off with faintly infuriating aplomb.

Polo Ralph Lauren Slim-Fit Polo Match Jean: While we wouldn't recommend white pants as ideal festival wear, Ronson's immaculate preppy get-up backstage at Lollapalooza was a triumph of style over substance. ($125.00 from RalphLauren.com)

Lacoste Short Sleeve Solid Pima Polo: If you're going to rock Ronson's youthful, Eurotrash-y take on yacht club chic, you may as well go for that classic of the genre, the Lacoste polo shirt. ($79.50 from Lacoste.com)

Risky Business Sunglasses in Black: Sure, Ronson's probably wearing authentic wayfarers (gotta spend that trust fund somewhere), but do you really want to walk around a rock festival with $150 worth of glass and plastic balanced on your nose? ($10.00 from FredFlare.com)
