5. "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." —Ilaria Urbinati, stylist

16. "The biggest mistake people make is making things personal instead of professional. If you have a golf coach and that person doesn't have much more to teach you, it's not a personal thing. You get a new coach. In the workplace, it's more like 'This is my new father.'
