What to wear to Main Square Festival: Arras sits at 23°C (73°F) by day and 14°C (57°F) at night in July, on city streets, with a high 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 rock, indie and streetwear, so anything that survives the day reads as right.
Men's festival dressing at Main Square Festival 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 city streets for 3 days.
The dominant aesthetics at Main Square Festival are rock, indie and streetwear. 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 3 days of city streets without you having to protect it.
What people actually wear: one good layer over a light base, because the temperature halves after sunset; the same jacket every day, because it lives in the tent and does everything.
