Men's Suits Guide

Men's suits are matched tailored ensembles - jacket and trousers cut from the same cloth, worn with a dress shirt and usually a tie - the formal grammar of Western menswear since the nineteenth century and still the uniform of consequence for weddings, courts, boardrooms and ceremonies. This guide ranges over cloth, construction and history - the suit explained as a system a man can buy once, correctly, and wear for a decade - with a photograph of classic tailoring below. This guide covers the styles worth knowing, the fit points that decide comfort, the fabrics and construction that separate a good buy from a regret, and the simple care that makes the garment last.

Cloth, Canvas and Cut: The Suit System

A suit is cloth, canvas and cut. Cloth is numbered in 'supers' - the fineness of the wool yarn - where honesty lives in the middle: Super 100s to 120s worsteds balance drape, durability and price for a working suit, while very high supers buy softness with fragility. Construction is the skeleton: a fused jacket is glued into shape, a half-canvas jacket floats a chest piece that molds to the wearer, a full-canvas jacket is the heirloom build - each step costs more and wears better. Cut is national and personal: British structure, Italian softness, American ease, all now cross-bred into the modern slim-but-not-tight silhouette. Color is strategy: navy and charcoal are the two-suit wardrobe entire, with grey flannel and seasonal cloths as the connoisseur's expansion. (Our sports coats guide covers the suit's odd-jacket sibling.)

The durable buying order is job, specification, budget - in that sequence. Decide what the garment must do, translate that into fiber, weight, construction and size numbers, and only then shop price. Read labels as specifications, inspect the garment inside out where finishing is unposed, and prefer the maker who publishes measurements to the one who publishes adjectives. A garment that matches your measurements, climate and laundry will be worn; one that misses any of the three becomes expensive storage.

Fit and Sizing

Suit fit is the most consequential fitting in menswear, and its order is fixed: jacket shoulders exactly at yours - the one unalterable - then the collar's hug, the button's clean close, sleeve to a half inch of cuff, length covering the seat. Trousers: waist seated without a belt's heroics, seat smooth, break slight over a polished shoe. Everything after shoulders is a tailor's afternoon; shoulders are forever, so a suit that fails there fails outright. Buy the best-fitting shoulder in the best cloth you can afford, and budget the alterations as part of the purchase - a finished suit is fitted, not merely bought.

Measure yourself once a year and keep the numbers - chest, waist, inseam, foot, head - because bodies drift gradually while size habits never do. Shop from measurements, try garments under real conditions (over layers, in your own shoes, late in the day for footwear), and be honest about alterations: lengths and small waist changes tailor beautifully; shoulders, rises and patterns are the garment you bought forever.

Wearing and Care

Suits are rested, brushed and aired more than they are cleaned: a day or two between wears on a broad hanger, a brush after each wear, dry cleaning a few times a year at most - each cleaning costs the cloth a little of its life - with pressing as the regular refresh. Store out of plastic, in a breathable bag, with cedar against moths. A well-bought suit maintained this way crosses a decade of occasions and comes out of the closet each time looking like the decision it was.

Five minutes when a garment comes off - shake it out, hang or fold it correctly, note the stain and the loose button - prevents most of the damage later blamed on quality. Keep a small kit where the clothes live: brush, lint roller, conditioner suited to your leathers, black, navy and grey thread. Clothing rarely dies at once; it fades by small neglects, and small attentions reverse the process at the same pace.

Formal suits have a ladder of their own: the dinner suit for the evening, and for the daytime the morning suit and its plainer brother the stroller suit.

Same Cloth, Four Colors, Four Ways to Buy

A suit is a set of garments made from the same cloth, usually at least a jacket and trousers, the top and bottom matching in color and pattern. (The classic tailoring photograph is in the gallery below.) The main four colors for business suits are black, light grey, dark grey and navy, solid or with pinstripes or windowpane checks, and the modern range has widened, with plaids such as the traditional glen plaid and herringbone accepted in the workplace and beyond. Suits are sold in several ways, from bespoke and made-to-measure to ready-to-wear.
