She doesn't have a reality series, and you won't see her dissecting Oscars attire on E!, but Ilaria Urbinati, 30, is the woman behind some of Hollywood's best-dressed men. The Italian-born, American-raised stylist counts Bradley Cooper and Giovanni Ribisi among her clients. She also co-owns Confederacy in Los Angeles, a store known for masculine staples and approachable high fashion. Here, she shares her tips for making every guy look like an A-lister.

Lose the Flair: Simplicity is the key to men's style. I like guys to look iconic and handsome. Leave elaborate stitching, whiskers on jeans, and wild prints to the Ed Hardy crowd.

Go Tonal: I love mixing various shades of the same color. I'll pair a navy suit with a slate-blue shirt and a blue tweed tie. The shades and textures should be different enough that you don't look like you were trying to match but failed. It needs to look intentional.

Get the Right T-shirt: A good fifties-fitting white crewneck is the sexiest thing a man can wear. It should be slim but not tight and fall just above your pants waist—no longer. Make sure the sleeves hug the shoulders and hit just above the biceps. Think Brando. I love Lo-Fi's rare vintage tees in white and army green.

Buy a Utility Shirt: I use work shirts a lot—two pockets with button-down shoulder flaps—because they look handsome on almost every guy. And they're great for my skinny clients because they add some extra build. Unlike with a regular oxford, you don't look like you're missing a jacket. Never wear a tie or blazer with a work shirt. Rag & Bone, Nom de Guerre, and Band of Outsiders make my favorites.

Anything Not Gray Is the New Black: I think gray is a little tired. You can't beat a slim, impeccably tailored suit in a nice dark color like midnight blue. Lately I'm into deep colors that could almost read as black, like dark greens, burgundies, and blue hues—navy looks richer than black.

Learn the Power of Three: A three-piece suit is always sharp on the red carpet, but even sharper at a wedding. By the end of the night, when you take off your jacket, you're not the sweaty douchebag on the dance floor with the rumpled untucked shirt. The vest keeps your look pulled together.

You Can Leave the Dress Shoes at Home: I like a suit with a good, solid, worn-in boot. It's manly and rugged and gives the suit a little swagger. No sneakers with suits unless you're under 19 years old, or in Weezer.
