Any tips on how to go about doing it right or as right as possible the first time? I will be visiting one of the MTM makers in NYC very soon and want to get a decent fit (especially shoulders) the first time. Sadly, I do not have any shirts that have a sartorial-esque fit to bring along to carbon copy. I realize it is a work in progress, but any tips from pros who go all the time would definitely help. I plan to take measurements at home before I visit and then compare with the in-house recommendations.
