Those who covet everything designer Stella McCartney creates will be eager to learn that they can invest in one of her t-shirts while also doing their bit for charity.

Stella McCartney has created the most fashionable charity t-shirt around for this year's Red Nose Day. Modeled by the likes of Keira Knightley and David Walliams and photographed Stella's sister, the famed photographer Mary McCartney, the fabulous t-shirts are available exclusively at TK Maxx.

As well as all the proceeds going to Comic Relief, the t-shirts have been wholly manufactured in Africa, with 100% fairtrade certified, organic cotton from co-operatives in Senegal and Burkina Faso.

Whether it's supporting orphans in Africa who've lost their parents to AIDS or helping older people in the UK who are abused by someone they should trust – Comic Relief will use the money you raise to help people in desperate need.

Supporting Comic Relief and modelling the t-Shirts, Keira said: "Red Nose Day helps countless lives for the better, both here in the UK and in Africa. I am really happy to be part of this year's activity to raise money and so excited to wear Stella's designs."

The actress looked like she was having fun posing in several guises for the photoshoot.

On Red Nose Day 2009 and her role in this year's campaign, Stella McCartney commented: "It's a real honour to be involved in such a tremendous cause and be a part of the Red Nose Day campaign 2009. The designs of the t-shirts were inspired by iconic images of iconic people by iconic photographers and adding an element of humour to them.

I wanted to focus on photographs where people are happy and create a charity t-shirt that would become a staple of a person's wardrobe."
