What to Wear to Main Square Festival

The practical guide: weather, ground, footwear, bag rules and a full packing checklist for 3 days in Arras.

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.

Assume rain. A packable shell in your bag costs nothing to carry and saves the weekend; a "cute" jacket that soaks through ruins two days.

Everything below follows from those numbers.

What to wear, look by look

Look 01

Jorts & Tank Budget-friendly

The masc summer default that actually survives 34°C: jorts, tank, cap.

It speaks the same language as the line-up (indie, rock and streetwear), so you read as part of the crowd rather than a visitor. Made for tarmac and long walks between stages. At 23°C (73°F) this needs a real layer underneath. Thermal base, not just a jacket. One catch: it does not like rain, so pack a shell you can throw over it.

Footwear

Best option here: Cushioned trainers or a low boot. You are on concrete for ten hours.

Avoid: brand-new shoes, heels, and anything you have not walked 10 kilometres in.

You will walk between 15.000 and 30.000 steps a day at a festival of this size, repeated over 3 days. Footwear is the only part of a festival outfit that can genuinely end your weekend, so it is the one place to spend money and break things in beforehand. Pack a second, dry pair for the campsite. Putting wet boots back on at 9am is the classic mistake.

Bag, glitter and gate rules

  • Bag size. Most festivals of this size cap bags at roughly A4 or require a clear bag at the main stages. A belt bag plus a small crossbody clears almost every policy. Check the official rules before you buy anything bigger.
  • Chains and studs. Long chains, spikes and metal-heavy accessories are refused at some gates. If a piece is central to the look, have a backup.
  • Glitter. Biodegradable only at a growing number of festivals; plastic glitter is banned outright at several. It is also, practically, the hardest thing to remove from a tent.
  • Camping. Whatever you wear on day one lives in a tent for 3 days. Pack in outfit sets, not individual pieces, and put each day in its own bag.

The packing checklist

  • Two tops per day (one gets ruined)
  • One layer for the night
  • Earplugs
  • Refillable water bottle
  • Portable charger
  • Sun cream or SPF stick
  • Baby wipes
  • A bag with a zip
  • Packable rain poncho
  • Dry socks, more than you think
  • Head torch
  • Second pair of dry shoes
  • Bin bag for wet clothes

Camping changes the whole calculation. Your outfits live in a bag on the ground for 3 days, in damp conditions, with no iron, no mirror and a 14°C (57°F) night to sleep through. Three rules from people who do this every year:

  1. Pack in sets, not pieces. One bag per day with the whole outfit in it. You will be getting dressed in the dark.
  2. Sleep clothes are separate and sacred. Never sleep in what you danced in. That is how a tent starts to smell and how you get cold at 5am.
  3. One jacket does everything. Pick the layer that works over every outfit, and accept it will be in every photo.

What not to wear

  • Anything suede or leather-soled. Wet suede is finished, and a leather sole on wet grass is an accident.
  • Heels of any kind. Grass, gravel and crowd crush. Platform boots give the height with a surface area that works.
  • Brand-new shoes. Ten hours on concrete in unbroken-in soles is the most reliable way to leave early.
  • Your good bag. Beer, mud, being sat on. Take the one you would not mind losing, with a zip.
  • One outfit per day, hung up. Nothing stays flat in a tent. Roll sets, and accept creases as part of the aesthetic.

FAQ

Start with the weather: 23°C (73°F) by day, 14°C (57°F) at night, high rain risk, on city streets. That points to a light base with one warm layer you can carry, plus broken-in trainers or boots. Style-wise the crowd leans rock, indie and streetwear.

Typical night lows are around 14°C (57°F), a drop of 9 degrees from the daytime high. Most people manage with one light layer.

Cushioned trainers or a low boot; the site is concrete and gravel. Expect 15.000–30.000 steps a day, plus the walk to the campsite.

No formal dress code. Wear what survives the day; the crowd is broad and nobody is checking.

Festivals this size usually limit bags to around A4 size, and some require clear bags at main stages. A belt bag plus a small zipped crossbody clears almost every policy. Always check the official rules for the current edition. They change year to year.

Rain risk is high in July at this location, and the site drains reasonably well. Regulars build the outfit around a packable shell rather than hoping for a dry weekend.

Pack per day in sealed bags, keep sleep clothes separate, and bring one jacket that works over everything. Add a head torch, a second pair of dry shoes and a bin bag for wet clothes. The three things people forget first.

The reliable formula here is a tee, a light overshirt and broken-in trainers, with a beanie and a small crossbody bag. See the full list of men's outfits below.

Yes, but bring biodegradable glitter. Plastic glitter is banned at a growing number of festivals and is close to impossible to get out of a tent, a car or your hair. Face gems are the lower-effort alternative and survive sweat better.

Main Square Festival normally takes place in July, running 3 days in Arras. Exact dates are announced by the organisers each year at www.mainsquarefestival.fr. Check there before booking anything.
