What to wear to Wonderfruit: Pattaya sits at 32°C (90°F) by day and 22°C (72°F) at night in December, on open field, with a low chance of rain. That means loose natural fabrics and real sun protection, broken-in boots or sturdy trainers, and a bag small enough for the gate rules. The crowd leans boho, costume and psy, so a full costume is the norm rather than the exception.
Women's outfits at Wonderfruit have to clear the same three hurdles as everyone else's. 32°C (90°F) by day, 22°C (72°F) at night, open field underfoot, with more options for solving them.
The dominant aesthetics at Wonderfruit are boho, full costume, psytrance and camp-practical. 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.
This is a costume festival, and that changes the maths: turning up in normal clothes is the conspicuous choice. Budget for one full look rather than three half-hearted ones, and make sure you can walk, dance and queue in it for eight hours.
What people actually wear: as little fabric as the venue allows, in natural fibres, with a bag small enough to forget about; the same jacket every day, because it lives in the tent and does everything.
