How to Choose the Perfect Suit: A Complete Buying Guide

Short answer: Choosing the perfect suit comes down to six decisions, in this order — occasion, fit, fabric, color, style details, and budget. Get the first three right and almost any reasonable color or style choice will look good; get them wrong and no amount of accessorizing will fix it.

Step 1: Start With the Occasion

Before you think about color or fabric, decide what the suit is actually for. A suit bought for daily office wear needs to be more durable and neutral than one bought for a single wedding; a suit for a job interview should skew conservative, while a suit you’ll wear to evening events can take more personality.

Primary Use	Best Colors	Priority
Everyday business	Navy, charcoal, mid-grey	Durability and a fabric that resists wrinkling through a full day
Job interview	Navy or charcoal, solid or subtle pattern	Conservative fit and color over anything trend-driven
Wedding (as groom or guest)	Navy, tan, light grey for daytime; charcoal or black for evening	Matching the season and time of day, not just personal taste
Formal / black-tie events	Black or midnight navy	Fabric quality — this is where a cheap finish shows up most
One suit to cover everything	Mid-grey or navy, solid, mid-weight wool	Versatility over any single occasion

Step 2: Get the Fit Right

Fit is the single biggest factor in whether a suit looks expensive or cheap — more than fabric, more than brand. Off-the-rack sizing assumes a standard body shape that few people actually have, which is why the same labeled size can fit two people completely differently. Check these five points on any suit before you commit to it:

• Shoulders. The seam should sit right at the edge of your shoulder bone — not before it, not past it. This is the one point that’s very difficult to alter later, so get it right at the fitting stage.
• Chest and waist. You should be able to fit a flat hand between your chest and the jacket when buttoned, with no pulling or X-shaped creases across the button.
• Sleeve length. The jacket sleeve should end around the wrist bone, showing about half an inch of shirt cuff.
• Jacket length. As a rough guide, the jacket should cover your seat and end roughly where your fingers curl when your arms hang naturally at your sides.
• Trouser break. A slight break (a small fold where the trouser meets the shoe) reads as classic; no break at all gives a more modern, cropped look. Either is fine as long as it’s a deliberate choice, not an accident of an off-the-rack length.

Step 3: Choose the Right Fabric

Fabric decides how the suit wears through the day and how long it lasts, not just how it looks in the mirror.

• Wool is the standard choice for most suits — it breathes, resists wrinkling, and holds its shape better than most alternatives. Weight matters: a lighter wool (around 220–260 g/m²) suits warm climates and year-round wear in mild weather, while a heavier wool (300 g/m²+) suits colder climates and adds structure.
• Wool blends (wool with a small percentage of stretch fiber, for example) trade a little bit of that natural drape for easier care and more give when moving.
• Linen and cotton are cooler and more casual — good for warm-weather or daytime events, but they wrinkle more easily and hold a crease less well through a full day.
• Fully synthetic fabric is the cheapest option and the easiest to spot: it tends to have a slight sheen under indoor lighting and doesn’t drape the same way natural fiber does.

A note on fiber content labels: In the U.S., any suit sold at retail is legally required to disclose its actual fiber content (e.g., “100% wool” vs. “wool blend”) under the Textile Fiber Products Identification Act, enforced by the FTC. See the FTC’s official labeling guide for what that disclosure is required to include. Checking the label is a fast, reliable way to confirm what you’re actually paying for, rather than relying on how a fabric feels on the rack.

Step 4: Pick a Color, Pattern, and Style

Navy and charcoal are the two most versatile suit colors — both work for business, most weddings, and semi-formal events, and both pair easily with brown or black shoes. Black is more formal and more occasion-specific (see our Black Suit Guide for a full breakdown of when it’s the right call). Once you’ve picked a base color, a subtle pattern — pinstripe, herringbone, a faint check — adds texture without reducing versatility, as long as it’s not too bold for the occasion.

On construction details:

• Single-breasted vs. double-breasted: Single-breasted (one column of buttons) is the more common, more versatile choice. Double-breasted (two columns) reads more formal and more fashion-forward — great for a distinctive look, less forgiving on a fuller build.
• Lapel style: Notch lapels are the standard, everyday choice; peak lapels are more formal and often paired with double-breasted jackets.
• Vents: A single back vent is classic and slightly more casual; double vents (one on each side) allow easier movement and are common on tailored, business-oriented suits.

Step 5: Finish With the Right Accessories

How to choose cufflinks for a suit

Cufflinks only work with a French-cuff (double-cuff) shirt — check that your shirt has the extra fabric folded back before buying any. For most occasions, match the metal to your other hardware (belt buckle, watch case): silver/steel tones for a modern, everyday look, gold tones for a warmer, more traditional look. Keep the design simple (a plain oval, knot, or small geometric shape) for business and interviews, and save anything more decorative or colored for weddings and evening events.

How to choose a belt for a suit

The simplest rule: match your belt to your shoes, not to your suit. A black belt with black shoes, a brown belt with brown shoes — the buckle should also match your other metal accents where possible. Keep the belt slim (around 3 cm/1.2 inches) and the leather smooth rather than heavily textured; a bulky, casual belt is one of the fastest ways to undercut an otherwise sharp suit.

How to Choose a Wedding Suit Specifically

A wedding suit adds two variables that an everyday business suit doesn’t have to deal with: the season/time of day, and whether you’re the groom, groomsman, or a guest.

• Daytime or outdoor wedding: Lighter colors — tan, light grey, soft blue — and lighter fabrics (linen or a linen-wool blend) suit the setting and keep you comfortable.
• Evening or indoor wedding: Darker colors — charcoal, navy, or black — and a slightly heavier fabric fit the more formal mood.
• As the groom: It’s reasonable to choose something a shade more distinctive (a subtle pattern, a peak lapel, a color that stands slightly apart from the groomsmen) so you read as the focal point in photos.
• As a guest: Stay a notch below the groom’s formality and avoid all-white or anything that could compete with the wedding party’s color scheme — check with the couple if a dress code is specified.

Step 6: Set a Budget — and Decide How You’re Buying

Three broad paths exist, and the right one depends on how often you’ll wear the suit and how much fit control you want:

• Off-the-rack: The fastest and usually cheapest option, but you’re limited to standard sizing and whatever alterations a tailor can manage afterward.
• Made-to-measure: Built from your own measurements onto an adjustable base pattern — a strong middle ground between speed, price, and true fit. This is what Gomon builds: your measurements go into an individual pattern rather than a standard size chart, with your choice of fabric tier and style details (collar, buttons, pockets).
• Bespoke: A fully hand-drafted pattern built from scratch for one person, usually over multiple in-person fittings — the highest level of fit and craftsmanship, and priced accordingly.

Your Suit-Buying Checklist in 7 Steps

1. Step 1 — Define the occasion(s) the suit needs to cover, and let that narrow your color options.
2. Step 2 — Check the fit at the shoulders first — it’s the hardest thing to fix after the fact.
3. Step 3 — Confirm the fabric and check the fiber-content label if quality is a concern.
4. Step 4 — Pick a color and pattern that fits the primary use you defined in Step 1.
5. Step 5 — Decide on construction details (single vs. double-breasted, lapel style, vents).
6. Step 6 — Choose accessories (cufflinks, belt, pocket square) that match your existing metal tones and shoe color.
7. Step 7 — Match your budget to your buying path — off-the-rack, made-to-measure, or bespoke — based on how often you’ll wear it.

Why Made-to-Measure Solves Most of This at Once

Every step above — fit, fabric, color, style details — is a separate decision when you’re buying off-the-rack, and each one is a compromise against a standard size chart. Made-to-measure collapses most of that: Gomon builds each suit from your own measurements, so shoulder, chest, and sleeve fit are handled at the pattern stage rather than left to post-purchase alterations, and you choose your fabric tier and style details up front instead of settling for whatever’s in stock. Standard production runs about 20 days, with a two-week expedited option available, and if anything needs adjusting on arrival, the process starts with alterations before anything else.
