Forget about grey: this is fifty shades of red. Try a deep wine-colored shirt with your charcoal business suit, or go for a berry shade with pinkish tones. Red blended with blue creates a luscious purple color — and of course, don't overlook the best of all reds, a truly bright scarlet.

You don't have to go all-out red. For a subtle warmth, choose one of our classic formal shirts with a fine stripe or small check. A windowpane or gingham check gives you a touch more color, or if you're feeling bold, go for a twill or Oxford shirt in a solid plum or ruby. When it's time to dress down, team your Ultimate Chinos with a sports-inspired polo or plain red t-shirt.
