Fashionistas will be able to swap their unwanted clothing for a selection of garments donated by Hearst Magazines' Cosmopolitan, Elle and Oxfam in a Comfort pop-up shop.
The Unilever detergent brand will be cleaning pre-loved items with Comfort Intense and promoting sustainable fashion along the way.
There will be styling workshops with Sairey Stemp from Cosmopolitan and Molly Haylor from Elle.
People can bring multiple items they no longer wear to swap for something new from the Cosmopolitan and Elle fashion cupboards. The pop-up will also provide individually priced items available without swapping. Moreover, guests can add their initials or favourite phrases to any item picked up at the shop with the on-site embroiderer.
All proceeds from the "Comfort swap shop" will be donated to the Prince's Trust. The pop-up will be open during 18- 22 July on Brewer Street in London's Soho.
Michele Vincitorio, brand manager at Comfort UK, said: "We know that our clothes can improve not just how we look but our state of mind in a positive way too and it’s important we show them the love they deserve."
The pop-up is being delivered by Hearst and Mindshare, with the creative idea by Ogilvy.
