A lot of it is common sense, but you gotta also remember that a lot of us (me included) have never done this before and there are some questions that arise that may have seemingly obvious answers to you that aren't obvious to somebody who has never even handled a tape measure before. I have to say that I have seen many times on this forum somebody post a fit pic of their new TOJ to get feedback that the fit is off, and immediately to B&S it goes. That must be heartbreaking and extremely frustrating to spend so much money and wait for so long to get something that is of amazing quality and have it not fit the way they hoped it would. The prospect of that happening to me has made me hesitate ordering, as is the case with others, I suspect. I know it seems like a lot of work to put something like that together, and everybody is crazy busy, but I'm sure it's not more work than the hundreds of sizing emails Drew has to deal with. I am also a big fan of the local measuring person idea that was floated a while back. If there were an official sizing person in LA, I would go tomorrow. Edit: Look at Uncontrol's situation. He has put down a lot of money to have a one-of-a-kind dream jacket made. He only has one shot at this. While I think his agony over the bicep measurements is a bit comical, I completely understand and I don't think it would be fair to tell him to "just use common sense." If Drew were in LA, I would be more than happy to put together a video with him for free (I'm a filmmaker, I have all the gear). We'd be done by happy hour.
