Women have it easy just wearing a simple non-white dress. But in summer, the men’s traditional dark suit can be a little warm, somber and predictable. For a city wedding, choose a light weight suit in gray, blue or a subtle pattern. Style it up with a sky blue, pink, mint green or lavender long-sleeved Oxford or poplin shirt. In the country, blazers and sport coats reign, paired with well-cut chinos. Seaside or resort? A tailored white shirt, colored chinos and a light-colored linen blazer. Keep everything understated. And crisp.
