Talk about a party.

This week, global trendsetter Kendall Jenner made loungewear look ever-so sexy, stepping out in comfort in New York City to attend Calvin Klein’s christmas-themed Pyjama Party, giving the brand’s signature cotton essentials a supermodel edge.

The uber-exclusive nightcap, which celebrated Calvin’s upcoming Holiday Collection, featured performances by New York locals Too Many Zooz, who together with an underwear-clad celebrity guestlist, proved that pyjamas have never looked this good.
