Each week I will present a post on the ins and outs of custom suits AND suits in general. For the complete guide, leave a comment!
Other then having no pockets, the above picture shows three general styles of pockets that are suitable for trousers.
For those that have a heavier/wider lower body, a straight pocket may be better suited as a slant pocket may have a tendency to puff out and appear bulky. However, the slant pocket is fairly common and traditional so it depends largely on individual preference. The seam pocket may suit any body type and still allow for a laissez-faire/hands-in-my-pockets pose.
