Jacket PocketThe most formal are jetted pockets, where the pocket is sewn into the lining of the jacket and only a narrow horizontal opening appears on the side of the jacket. These pockets, being nearly invisible, contribute to a very sleek, polished appearance, and are most frequently found on formal-wear. The next style, the flap pocket, is slightly less formal, though it is perfectly acceptable in all the circumstances where a gentleman is likely to be found in a suit. Flap pockets are made identically to jetted pockets, but include a flap sewn into the top of the pocket, which covers the pocket's opening. These are the most common pockets on suit jackets, and in the very best, are fabricated so that the wearer may tuck the flaps inside, mimicking the jetted pocket. There are also diagonally-cut flap pockets known as hacking pockets, though they are somewhat less common; the hacking pocket is derived from English riding gear, and is most prominent on bespoke suits from English tailors, particularly those traditionally associated with riding clothes. The least formal are patch pockets, which are exactly what the name implies: pockets created by applying a patch to the outside of the jacket. Patch pockets are the most casual option; they are frequently found on summer suits that would otherwise appear overly formal, as well as on sports jackets.
