Bradley Cooper's style vacillates between basic bro and leading man depending on where he's headed. While the actor might wear navy trousers with, say, a peacoat and boots in his regular life, he's more than willing to turn up the swankiness for the pages of GQ. It goes without saying that you can wear your blues just the same way, especially if you're headed somewhere where you want to impress—whether that's Thanksgiving dinner at the in-laws's or an off-campus work meeting. This treatment of the wardrobe staple is smarter and more sophisticated than usual, which makes you look smarter and more sophisticated than usual. See how that works?
Start with a navy knit polo or cashmere crewneck on top and a pair of leather loafers on bottom. That's a trick you can use beyond this specific fit: If you want to make any pair of pants in your closet look a little more expensive and polished, pair them with a fine knit in the same color.
To finish the look, slip on a leather jacket. But leave your beat-up, Brando-in-The Wild One black jacket behind, and swap in a pared-down version—brown works great here. That'll give the whole thing the kind of swagger your trusty peacoat can't touch. Add one or two accessories to take the whole thing home. Cooper's aviator sunglasses and pendant necklace are a little bit badass fashion cop; a pair of square shades and a pinky ring will have more of an legendary Italian actor effect. Both are infinitely cooler than guy from the office, which is the entire point here.
