I need one of these "underground" t-shirts ($87) by Italian brand 5Preview. I love the reference to classic fashion brands and icons and the general irreverant nature of their designs.
Unfortunately my favorite design with the chanel logo appears to be out of production. Hopefully a version will be available again.
Besides t-shirts they also make tote bags and big chunky necklaces. You can check out all their wares at the 5Preview webshop on bigcartel.com.
You can also find some of the 5Preview designs on the I don't like Mondays webshop.
