Harvey Nichols has joined forces with fashion blogger Disneyrollergirl for new charity venture the Secret Tee's Project.

Seven of the London girl's favourite creatives, including Bip Ling and Sophy Robson, have styled exclusive t-shirts to be auctioned on eBay, with the identity of the designer only being revealed after the final bid. Bidding closes September 18 and all proceeds will be donated to the charity Kids Company.
