Channel 4 Education has launched a free online fashion community site and application, closet swap, created by Inensu.

The app encourages users to upload pictures, tag existing Facebook photos, and build an online closet which they can share, swap and even customise, in order to boost their wardrobes without spending money.

Paulina Bozek, founder of Inensu, said: “Fashion has always been a social activity that you share with friends and with Closet Swap we have created a must-have fashion app with a positive message that champions personal style over disposable fashion.”

The project is part of a wider theme for Channel 4 Education, highlighting the debates surrounding sustainable and ethical fashion production and consumption. Earlier this year, Channel 4 Education launched Sweatshop, an online game in which players run an off-shore factory, getting to grips with managing staff, suppliers and sales.

London accessories manufacturers Tatty Devine and vintage style icons Broken Hearts DJs have already signed up to offer pieces to lend from their personal wardrobes, with founding Tatty Devine designer Rosie, saying: “We often swap clothes with each other at Tatty Devine, and the main message of our new craft book is 'one girl's trash is another girl's treasure'. Swapping, reusing and customising are how we started Tatty Devine. We firmly believe in the power of the swap, so we'll be signing up to Closet Swap and sharing our accessory collections.”
