Hedi Slimane continues to mine authentic, pre-power-shoulder Yves Saint Laurent with his latest collaboration. The L.A.-based designer has teames up with the artist-musician Grimes (Claire Boucher) on a five-piece T-shirt collection. Inspired by Monsieur’s Love Posters from the 1970s (he was an tireless scribbler), Grimes’ alterations include mythical creatures and tribal heads framing the words “Love” and the trademark “YSL.”
