Wear a hoodie

BUT NEVER, EVER, PUT THE HOOD UP — Tricky territory for adults but worn correctly a hoodie can look cool and understated. Avoid disasters with a dark style teamed with a first-rate T-shirt and classic soft overcoat in tonal shades. Alternatively, go for a statement shade top under your everyday suit. Two rules: never wear the hood up, even if it’s raining; and make sure it’s relatively fitted.
