What to wear to Life is Beautiful: Las Vegas sits at 33°C (91°F) by day and 21°C (70°F) at night in September, on city streets, with a low chance of rain. That means loose natural fabrics and real sun protection, cushioned trainers or a low boot, and a bag small enough for the gate rules. The crowd leans streetwear, y2k and urban, so anything that survives the day reads as right.
