What to wear to When We Were Young: Las Vegas sits at 26°C (79°F) by day and 14°C (57°F) at night in October, on arena grounds, 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 punk, alt and goth, so anything that survives the day reads as right.
Women's outfits at When We Were Young have to clear the same three hurdles as everyone else's. 26°C (79°F) by day, 14°C (57°F) at night, arena grounds underfoot, with more options for solving them.
The dominant aesthetics at When We Were Young are punk, alternative, gothic and Y2K revival. 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.
There is no enforced dress code. What the crowd rewards is a look that survives 1 day of arena grounds without you having to protect it.
What people actually wear: one good layer over a light base, because the temperature halves after sunset.
