Artist and designer Johny Dar is gathering denim duds from the likes of Kate Moss and Anna Wintour for an art project and fundraising initiative with all proceeds going to benefit refugees through a donation to the International Rescue Committee.

One hundred celebrities—spanning the worlds of art, music, fashion and sports— will donate a pair of jeans to be painted by Dar during a week-long live art performance that will take place at a refugee camp. Dar will paint continuously during this length of time, reflecting the endurance needed by refugees.

The pieces will be exhibited for a week at the Saatchi Gallery in London from Aug. 22-28, 2016. At the end of the exhibition, the pieces will be auctioned at a fundraiser and all proceeds will be donated to the IRC initiatives.

Participants in the project include Bella Hadid, Candice Swanepoel, Carl Cox, Carla Bruni, Cat Stevens, Catherine Deneuve, Chanel Iman, Claudia Schiffer, Daniel Radcliffe, Elle McPherson, Elton John, Emma Watson and many more.
