I like both looks. It depends on the circumstance: If the jacket has a ticket pocket, flaps are a must. If I purchase a RTW item that is Regular and not Short, I normally look for a jacket that has besom pockets, since when the length of the jacket is cut, the obviousness of this is less apparent than with flap pockets. At the same time, opened besom pockets tend to sag after a while, especially when regularly used. With a flap however, the same sagging is not noticeable, since it covers the pocket. Jon.
