What to wear to Colours of Ostrava: Ostrava sits at 25°C (77°F) by day and 14°C (57°F) at night in July, on industrial site, with a moderate 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 indie, industrial and boho, so anything that survives the day reads as right.
