wants us all to do something funny for money – wear her designs to raise it for Comic Relief, to be exact.

The award-winning London designer has created a line of charity T-shirts exclusively for TK Maxx in aid of Red Nose Day, which takes place on 15 March. And she’s gotten all her celebrity friends – and ELLE – in on the act.

ELLE’s fashion features director Rebecca Lowthorpe was invited along to the campaign shoot for the Ts, which feature black-and-white images of icons such as Marilyn Monroe and The Beatles, with a touch of Stella humour in the mix. Kate Moss models, while Stella’s photographer sister Mary, along with Helena Christensen, is behind the lens.

‘When I do something like this I just get really involved,’ Stella explains of the process. ‘You want to make it the best you can for them, not just, “OK, here’s your T-shirt, good luck.” I wanted Kate to do it and I wanted Mary to do it and make it as good as we can and proud of it.’

Get yours, pronto: the range is on sale at TK Maxx stores nationwide and at TKMaxx.com now, with prices from £5.99 for children's and £9.99 for adult sizes. And don't forget to buy your new-look March ELLE for the full, inside story.
