What to wear to Lollapalooza Argentina: Buenos Aires sits at 27°C (81°F) by day and 18°C (64°F) at night in March, on open field, with a moderate chance of rain. That means a light base with one warm layer you can carry, broken-in boots or sturdy trainers, and a bag small enough for the gate rules. The crowd leans y2k, streetwear and indie, so anything that survives the day reads as right.
