Before selling to a single customer, we compared our technology to a group of professional tailors. We measured a group of people with those tailors and found our technology to be 20% more accurate than the average tailor. In statistics terms, we found that MTailor's measurement for any given person was 20% closer to the average of all the tailors' measurements than any average individual tailor.That, and more than 100,000 satisfied customers from over 50 countries, is why you can be confident that you'll receive a perfect fit from us!
