Suit and Sportcoat sizes are denoted with a number and a word (42 regular, for example). The number corresponds to your chest measurement; the word describes the length of the jacket, which depends on your height (please see chart below).
To measure your chest, place your arms at your sides and have someone take a measurement under the armpits and around the broadest area of your chest. The tape measure should be held so that it is neither tight nor loose. Unless otherwise notated in the product description, our suits have a six-inch drop, which means that a size 40 jacket will be paired with a size 34 waist pants.
