For some time now, everyone's been proclaiming that 30 is the new 20, but Calvin Klein Underwear has nothing to fear, as it looks as fresh as ever, three decades on. Last weekend the brand fêted its birthday with a glamorous seaside party, and as it just so happened to coincide with New York's Gay Pride festivities, the brand joined forces with NYC Pride as a sponsor. Bartenders poured drinks—lots of 'em—clad in Calvin Klein, and go-go dancers gyrated in hyper-colored Bold briefs. The entrance to the legendary Pier Dance featured an installation of bronzed hotties modeling their goods (we mean the skivvies, we swear) on an industrial scaffolding. Happy birthday, CK! Flirty thirty fits you well.
