What to wear to Lollapalooza Berlin: Berlin sits at 20°C (68°F) by day and 11°C (52°F) at night in September, 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 streetwear, techno and y2k, so black and functional reads as insider.
