If you want to look good, one of the easiest ways to do so is by simply making sure that your clothes fit well. But it’s not cheap — going to a tailor to get a shirt fitted and made costs real money.

Y Combinator-backed MTailor wants to change that by offering affordable, custom-fit clothing. It can do that because it removes much of the cost associated with taking customers’ measurements by measuring them via mobile apps.

MTailor is a new kind of fashion company, one which enables customers to design and purchase premium, tailored shirts for just $69 each. That’s well below what one might expect if they went to a tailor to have a shirt fitted, and even less than some people will pay if they were to buy a dress shirt off the rack from a department store.
