What to wear to Pukkelpop: Hasselt sits at 23°C (73°F) by day and 14°C (57°F) at night in August, 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 indie, alt and streetwear, so anything that survives the day reads as right.
Men's festival dressing at Pukkelpop comes down to three decisions: how much you can take off when it hits 23°C (73°F), what you put back on at 14°C (57°F), and whether your shoes can take open field for 4 days.
The dominant aesthetics at Pukkelpop are indie, alternative, streetwear 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.
There is no enforced dress code. What the crowd rewards is a look that survives 4 days of open field without you having to protect 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.
