When Calvin Klein sent this sweatshirt down the catwalk in January, as part of the autumn/winter 2014 collection, the fashion world went crazy for them. They will probably be the most coveted sweaters for the new season, and Harry Styles, the lucky so and so, gets his mitts on this one for Radio 1's Big Weekend.OBSESSION is appliquéd to the front, one of the names of Calvin Klein's best selling fragrance. The others in the collection read 'ESCAPE' and 'ETERNITY'. I bet Harry has these too, ready to pull on at any given moment. When he likes something, he really sticks with it. Those tan suede Saint Laurent boots for example... hardly any tread left on them! And he slightly over did the whole Burberry heart print thing.This is one wardrobe piece I am SUPER envious of though. I'm going to just say it... I'm OBSESSED with it (soz about that!). Can't wait to buy one! (on sale probably from August/September)
