that's a personal preference, I hate cuffs pulling up like you've shown there. especially with a SC/suit because then I have to deliberately reach in and pull them down again.
also, a trick of mine is that if you find there's some billowing out at the placket (with MTM you should be able to get it quite narrow here so it shouldn't be the case), I get my placket button moved over slightly to trim that part of the sleeve.
Great info, thanks!
Realistically, though, you never get to extend your arms like that IRL (other than driving... and I drive without my suit jacket on). Also, considering that a person who gets MTM shirts will also have his suit jacket cuffs altered, there's also little chance his jacket cuffs will be too long, as you said in an earlier post.
But given the fact that the shirt will shrink with a couple of washes, I will lengthen the cuffs as per your suggestion.
