What to wear to Field Day: London sits at 23°C (73°F) by day and 15°C (59°F) at night in August, on city park, with a moderate chance of rain. That means a light base with one warm layer you can carry, cushioned trainers or a low boot, and a bag small enough for the gate rules. The crowd leans techno, underground and streetwear, so black and functional reads as insider.
