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.
Men's festival dressing at Oktoberfest comes down to three decisions: how much you can take off when it hits 18°C (64°F), what you put back on at 9°C (48°F), and whether your shoes can take city streets for 16 days.
The short version: Tracht: dirndl or lederhosen. Cheap costume-shop versions are spotted instantly by locals.
The dominant aesthetics at Oktoberfest are full costume, party, quiet elegance and americana. That is the visual language of the site, the stages, the merch, the crowd photos, and outfits that speak it look intentional rather than borrowed.
This is a costume festival, and that changes the maths: turning up in normal clothes is the conspicuous choice. Budget for one full look rather than three half-hearted ones, and make sure you can walk, dance and queue in it for eight hours.
What people actually wear: one good layer over a light base, because the temperature halves after sunset; something identifiable, a colour, a hat, a flag, so your group can find you in a crowd of that size.
