I have a new Canali houndstooth sport coat that I took to the tailor for alterations. I always find sport coats and suit jackets too long, by about 1 inch. I like to have them shortened so that they arrive to my middle knuckle. They usually come almost to the fingertip when I buy them, and that is too long for my tastes. This coat is double-vented and my tailor blanched when I asked him to shorten it. He said the double vents would look funny if he shortened the coat because the vent openings won't be long enough. I told him to go ahead and shorten it. I figure I would rather have the coat be the right length and the vents an inch shorter than have nice long flapping vents and a too-long coat. One of the things to be said for bespoke, I guess.
