A tailoring term for the back pockets on pants or trousers. These pockets are typically constructed as patch pockets on casual wear like denim, or as welted pockets on formal trousers. The placement and angle of the flank drastically affect the visual shape of the garment's seat.
Heard on the job
Make sure the flank pockets are perfectly symmetrical before you topstitch them to the denim.
