In this article we will discuss the parts that make up a man’s suit. Although off the rack suits afford you little flexibility in adjusting these parts, the man who goes with a bespoke or made to measure suit has the freedom of choosing the option that best compliment his body. In any case, all men should understand the basics of the suit and its parts so that they buy a garment that accentuates their most positive traits.
Single or Double Breasted
The first and perhaps most noticeable element of the suit is whether it is single or double-breasted. Single-breasted suits have a single row of buttons down the front, and the jacket flaps only overlap enough to permit buttoning. A double-breasted suit has two rows of buttons, and the front overlaps sufficiently to allow both flaps to be attached to the opposite row of buttons. The choice between single- and double-breasted is a matter of personal taste, though the vast majority of American men choose single breasted suits as that this is what is readily available to them; also a lack of familiarity with the double-breasted option may account for the single-breasted suit’s dominance. Thin gentlemen, particularly those who are somewhat taller, can benefit greatly from double-breasted suits, as they will give a fuller appearance to the figure; on larger men, double-breasted suits can have a tendency to draw attention to the midsection, so careful attention and an expert tailor should be employed.
Lapels
Lapels come in a variety of styles with a number of options. The lapels’ width is perhaps subject to the most variance, with the extremely narrow lapels of the 1950s standing in stark contrast to the excessively wide lapels of the 1970s. As is the case with much of classic fashion, the most timeless lapels are of a moderate width. In addition to different widths, suit lapels come in two styles: notched, which has a wide V-shaped opening where the lapel and collar join; and peaked, which flares out in a sharp point with a very narrow deep V at the join. Notched and peaked lapels are equally classic, though the latter are most commonly found on double-breasted jackets. A peak lapel on a single-breasted jacket is an excellent way to raise its level of formality, but is almost impossible to find on anything but a custom made suit
Waist Buttons
A suit jacket has either one row of buttons or two, depending on whether it is single- or double-breasted. A single-breasted jacket has a single row of buttons, numbering anywhere from one to four, though two and three are the most common. The three-button jacket is the most traditional configuration, taking its cue from English riding jackets; properly worn, it gives the illusion of height. Traditionally, only the middle or second button is fastened when standing, though the top two buttons may be fastened to produce a slightly more formal appearance. Two-button suits are a slightly later innovation, and because they show more of …
