Dickeis Men's Sizing Information
Measurements refer to body size, not garment dimensions.

Slim Fit: Slim fitting, sitting close to the body, great for showing of your guns and pecks.
Regular Fit: Neither slim nor oversized. Regular-fitting garments that are bang in the middle. The middle is good.
Relaxed Fit: Drapes loosely on the body, baggy fit.
Neck Mesurement Place the measuring tape around the neck at the height where the collar would normally rest. This will be just below your Adam's apple. Stand relaxed. Do not crane your neck out or squeeze your chin down. The tape should be resting lightly on the skin, not squeezing it. Hold one finger under the tape measure to ensure some room for comfort. Do not try to account for shrinkage by adding extra here.
1ChestRun the tape around the fullest part of your chest, the tape should be just below the arm pit and over the shoulder blades whilst horizontal to the floor.
2WaistMeasure around your natural waist as show in the diagram
3InseamMeasure your inside leg from crotch to ankle blone keeping your leg straight: not as easy as it sounds, you could take a pair of trousers that you already own, that fit you well, and measure from the crotch to the bottom of the leg.
4SleeveThis is a bit more tricky! Measure from the top of your spine (at the bottom of your neck) to your elbow and on the your wrist
5ArmYou should place the beginning of the measuring tape behind your shoulder, and feed it out following your arm making sure to pass both the elbow joint and the wrist, as pictured. You should take the measurement at the point where you would like the sleeve to end. This is usually just past your wrist.
