MTailor is a YC company that makes a mobile app that will take your measurements via video and deliver you a custom made shirt or suit. (Disclosure: I funded them at YC). I've personally had good results with the shirts, waiting on a suit now. It is very competitively priced (I've actually told them repeatedly to raise prices!). I've gotten custom shirts from other tailors but prefer buying from mtailor now because of the ease of it.
