What to wear to Dour Festival: Dour sits at 24°C (75°F) by day and 14°C (57°F) at night in July, on open field, with a high chance of rain. That means a light base with one warm layer you can carry, waterproof boots, and a bag small enough for the gate rules. The crowd leans alt, rave and underground, so anything that survives the day reads as right.
Men's festival dressing at Dour Festival comes down to three decisions: how much you can take off when it hits 24°C (75°F), what you put back on at 14°C (57°F), and whether your shoes can take open field for 5 days.
The dominant aesthetics at Dour Festival are alternative, rave wear, underground and camp-practical. 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 function-first crowd. Black, utility and good shoes read as insider; heavy glitter and fancy dress read as tourist. Nobody is stopping you, but you will feel it.
What people actually wear: one good layer over a light base, because the temperature halves after sunset; wellies or waterproof boots on almost everyone by day two; the same jacket every day, because it lives in the tent and does everything.
