This is really cool! I'd love to see this become mainstream with second-hand and slow fashion communities :)
Like where people could remix looks and then publish them, a bit like polyvore was once a long time ago.
So slow fashion aims to be the opposite, to slow consumerism (sustainable working conditions, materials, emphasis on locality where possible, etc). Obviously more expensive as new clothes removes the mass production [sweatshop] element and uses higher quality materials that won't fail as quickly. As sibling comment says second hand clothes are major part of this
