Miu Miu's mustard shorts remind us of the colorful pairs that high schoolers would wear to gym class in the '70s, but a little more forgiving. Made from lightweight wool and mohair-blend, they have a drawstring waistband that sits comfortably high and off-white trims that outline the loose shape. Pair it with a cotton blend t-shirt. Accessorize with Adidas sneakers and a black backpack.
