4) Kukuxumusu T-Shirt

Ok, I know you're going to buy a t-shirt, so why not get one that isn't really, really tacky? Kukuxumusu is a Spanish t-shirt brand with some very imaginative and often quite silly t-shirts drawn in the Basque company's distinctive style. A lot more fun than then "I love Madrid" t-shirts and something that you might actually wear out! The t-shirts can be found all over Spain, while they have a store near the opera house in Madrid (Metro: Opera)
