The basic white tee is despite its simplicity one of the most classic pieces out there – all the way up next to the little black dress and pair of 501′s. First embraced by American seamen in the 1940s, the tee was wildly popularized through Marlon Brando, who in his role in The Wild One showed that all you need to be the sexiest man on earth is some cotton around your pecks. Since, from Juliette Greco and James Dean, to Brigitte Bardot and Calvin Klein-era Brooke Shields, the simple garment has cemented itself in our collective unconscious as the best example of casual cool. Acclaimed fashion photographer Mario Testino has been celebrating the white tee through his T-Shirt Collection, a photographic series he recently took to our side of the world, to Copenhagen and its many tender-looking faces. In total, nine Danish models – including Klara Kristin, Olivia Therese, and DANSK alum Kirstin Liljegren and Sylvester Ulv – features in the series, which was revealed on Testino’s personal platform Mira Mira today. “It begs the question,” he notes on his site – “when everyone has a white tee, what makes you stand out?” Find out here.
