STYLE SLEUTH: LIKETOKNOW.IT

It’s a social-based shopping service that allows users to purchase whatever their favourite influencers are wearing – in an instant. It works like this: just download the app; go on Instagram, if you see @liketoknow.it tagged in the post of an influencer’s page, screenshot it; go back to the app and, hey presto, click on what the influencer is wearing and you’ll be taken to the website where you can buy it. Its trackability. It allows retailers to see exactly how many referrals each influencer generates, which in turn allows influencers to benefit by monetising their social-media posts (far easier to charge an accurate fee-per-sponsored post when results are quantifiable). No wonder the app already has more than 1.4 million registered users and 3.1 million Instagram followers.
