That sleeve is too long, shirt or no shirt. This is a frequent frustration I have with American alterations tailors. I think many of them were trained not to show any cuff at all. I sometimes have to argue with them to get them to make my sleeves high enough. (I personally prefer half and inch of cuff.) In the end it’s your jacket and you’re paying them to get it the way you want it.
This is also what surprised me (here in Denmark): Both the salesman and the unrelated (alteration) tailor wanted the sleeve to be pretty long. So I see having them properly shortened as a way to stand out positively. I just hope it will not end up as standing out negatively, if everyone else perhaps shows no shift cuff! (I'm starting a job at a consulting firm next month).
By the way, my tailor's reason for not shortening further was that when I extend my arms forward, I will show plenty of cuff. But I think it's much better to show a little cuff at rest and then plenty plus that little extra bit when extending my arms fully forward.
