The Offset Warehouse, probably the biggest distributor of eco- and ethical-friendly clothing, are doing their bit to raise awareness. They've launched the "Still Alive" t-shirt, which boldly puts its status as cruelty-free wear front and centre. There's a nod to Katherine Hamnett's classic protest t-shirt designs in the strong, sans serif text and simple, direct message. It also makes an uncomfortable point in a clear fashion: it'll probably be one of the few items in your wardrobe that you can be totally certain has been made in an ethical manner. The t-shirts are made in factories where the employees are treated and paid fairly, and all the profits will go towards supporting the rights of garment workers worldwide.
They're under a fiver, which I'd say is well worth the investment. Show your support for garment workers rights, and look good doing it.
