Anyone who’s just pulled an all-nighter might start to feel a little wonky right now, but comfort can come from knowing you’re totally fashion. One look emerging at London Collections Men is what we have dubbed: ‘party face’. Think that glow - aka a thin film of sweat - that comes from spending all night dancing at a rave, as seen at Lou Dalton. Or the unapologetically sweaty hair at Rory Parnell-Mooney. Arguably the most mood-appropriate ‘party face’ hair style came at Christopher Shannon, who referenced Marbella in his show notes. Models had visible foam smooshed into their hair, as if they had just emerged, blinking into the Spanish light, from a foam party. And if that isn’t a good excuse for an all-nighter, we don’t know what is.
