What to wear to Oktoberfest: Munich sits at 18°C (64°F) by day and 9°C (48°F) at night in September, on city streets, 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 costume, party and elegant, so a full costume is the norm rather than the exception.
