MTailor makes a lot of promises, but by most accounts, we believe them. The new iOS app uses your phone’s camera to take your body’s measurements, which are then used to create a custom shirt for you in the material of your choice for an affordable price. According to MTailor, the app measures you 20 per cent more accurately than a professional tailor, making for one hell of a nicely-fitting shirt at a price that would make a bespoke craftsman blush. If you don’t like it, they’ll remake it for free. Smartly, the support staff uses each dud shirt to tighten their app’s measurement algorithm in order to make future shirts fit even better. Oh, and they always ship for free.
