The pockets of a suit jacket or sportcoat may be great for holding keys and change, but there’s more to them than just function. A different style of pocket can radically change how a jacket looks and is perceived, which makes them a key customization.

Standard Flap

File under “can’t go wrong.” Flap pockets are the most common type of pocket by a mile. While they’re the expected choice for a business suit, they don’t look out of place on more casual suits or sportcoats either.

Slanted Flap

Less common are slanted flap pockets, which are positioned at a slight angle. This style of pocket has its origins in English horse riding, as the curve of the pocket made it easier to access while mounted on horseback. As a result, it’s a bit more casual than the standard flap.

Ticket

Another hand-me-down from the English, the ticket pocket is a smaller, third pocket paired with two flap pockets. It was originally intended to hold the tickets of London theatergoers, but in modern times has proved an excellent match for a smartphone. It’s a bit more formal than the standard flap arrangement and grants any coat a bit more personality.

Jetted

Jetted pockets are essentially flap pockets—minus the flap. They give a jacket a sleeker, more modern look.

Patch

The most casual style is the patch pocket, which is made of extra material sewn onto the outside of a jacket. Its additional holding volume gives jackets a sort of “country look” that’s great for tweeds, linen, and other more casual fabrics.
