Center vents are "incorrect" and seriously bad on DB coats. Â They completely throw of the symmetry. Â If you buy that coat, I strongly recommend having the vent sewn up. Â On that kind of lean silhouette, no vents would probably look better than two vents in any case. Just curious: do you see many DB coats with center vents in the UK? Â I thought only Americans were sartorially out of touch enough to do that. Â All the DB coats I see in London are double-vented.
