This blue, yellow and black cotton Marni T-shirt features short sleeves, a round neckline, dropped shoulder seams and a straight hem. Crafted in Italy from 100% cotton, the contrasting sleeve adds just the level of quirk that one would expect from those mavericks over at Marni. What's more, don't relegate the humble tee to weekends and trips to the shops. After all, as the great Karl Lagerfeld said: "You can be the chicest thing in the world in a T-shirt and jeans." So that's all the permission we need to style our Marni tee with Maison Margiela and Prada.
