Amsterdam hosts 5 festivals in this guide, in North Holland: DGTL Amsterdam, Milkshake Festival, Dekmantel Festival, Loveland Festival, Amsterdam Dance Event.
Amsterdam has 5 festivals in this guide. They run in April, July, August and October, and festival-day temperatures range from 13°C (55°F) to 23°C (73°F), with nights down to 6°C (43°F). That range is the reason there is no single "Amsterdam festival outfit". The answer changes by month and by site.
2 sit below 16°C, where the outer layer effectively is the outfit. 2 carry a high rain risk, which makes waterproof footwear a requirement rather than a precaution.
The ground matters as much as the sky. You will find industrial site, city park, forest and city streets, 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 techno, underground, glam and streetwear. Amsterdam Dance Event is the largest of them at around 450,000 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.
