What to wear to Tomorrowland Winter: Alpe d’Huez sits at 3°C (37°F) by day and -6°C (21°F) at night in March, on snow, with a moderate chance of rain. That means thermal layers under a statement outer layer, insulated waterproof snow boots, and a bag small enough for the gate rules. The crowd leans snow, apres-ski and rave, so a full costume is the norm rather than the exception.
