São Paulo hosts 1 festival in this guide: Lollapalooza Brasil.
São Paulo has 1 festival in this guide. They run in March, and festival-day temperatures range from 27°C (81°F) to 27°C (81°F), with nights down to 19°C (66°F). That range is the reason there is no single "São Paulo festival outfit". The answer changes by month and by site.
1 carries a high rain risk, which makes waterproof footwear a requirement rather than a precaution.
The ground matters as much as the sky. Every festival here is on arena grounds, which puts broken-in trainers or a low boot at the top of the list for most of these events. None of them have camping on site, so you are travelling in and out each day and the outfit has to survive the journey at both ends.
Stylistically the crowd here leans y2k, streetwear, pop and glam. Lollapalooza Brasil is the largest of them at around 100,000 people, and it sets the tone the smaller ones react to. None of that is a dress code. It is what you will see, which is worth knowing if you would rather blend in or deliberately not.
