Celebrities including Mollie King, Rachel Riley, Louisa Johnson, Vogue Williams, Lydia Rose Bright, Roman Kemp and Ashley James have teamed up with Jeans for Genes to star in its 2017 campaign, promoting the fundraising day on September 22 and the charity's new limited edition t-shirt, which was hand-picked from several entries by Kate Moss.

King commented 'I'm really pleased to be part of a fantastic charity campaign that helps to change the lives of children with life-altering genetic disorders. Fundraising for Jeans for Genes Day is obviously the primary purpose, but it is also a really fun initiative giving us a chance to experiment with denim! I’m looking forward to wearing my favourite jeans in support of the campaign on Friday 22 September, and I hope others are too'.
