What to wear to Portola Festival: San Francisco sits at 21°C (70°F) by day and 14°C (57°F) at night in September, on city streets, with a low 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 techno, house and urban, so black and functional reads as insider.

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. 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.

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.
  • No camping. You are travelling in and out each day, so the outfit has to survive public transport at both ends, and a cloakroom is not guaranteed.

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

What not to wear

  • 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.

FAQ

Start with the weather: 21°C (70°F) by day, 14°C (57°F) at night, low 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 techno black, house and urban.

Typical night lows are around 14°C (57°F), a drop of 7 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.

No formal dress code. In practice the crowd wears black and dresses for function, and standing out is a choice you make deliberately.

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.

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.
