Ah, good old Styleforum. Where the correct length of a coat can be assessed, from the front, down to half inches. It doesn't look too short to my eyes or my taste. And since coat length is, up to a point, a matter of taste, I dare say it's not "too short." It's certainly not so short as to appear ridiculous -- it's not even short enough to appear fashion forward (or even in line with the majority of jackets now sold RTW in Italy).
