One of the most, if not the most overlooked alteration of a mans jacket are the sleeves. Ideally, the sleeves should end at the break of the wrist, leaving 1/4-1/2 inch of sleeve showing. A much better aesthetic is achieved with a bit of cuff showing, in a sense framing a mans jacket. On the picture above the sleeves are too short, it looks unrefined and careless. However, in the picture below the sleeves are pinned to a proper level (you will also notice that the bottom of the jacket has been pinned up, but more on that another time). Just don’t forget to get the buttons on the sleeve moved up, ideally they should be about 1 1/4 inch from the sleeve head. (And also as a disclaimer, that is not the outfit to wear with a jacket like that, it just happened to be what was worn the day I went to the tailor).
