Bespoke Menswear — Size Guide
Our Contemporary Regular blazers are cut to a slim-leaning silhouette with European proportion — clean through the chest, with a defined 6-inch waist suppression. This guide will help you identify your size with confidence.
Slim-leaning, not slim. More structured than a sack coat, less restrictive than a fitted cut. Built for the man who moves.
Every measurement in this chart has been validated against ASTM D1835 standard body data and verified in live fit sessions.
Sizes 38 through 60, Regular and Long lengths. Graded evenly across the full range — no size is an afterthought.
Use a soft tape measure. Wear a dress shirt (no jacket). Keep the tape snug but not tight — you should be able to slide two fingers underneath.
Measure around the fullest part of your chest, just under your arms and across your shoulder blades. Keep the tape horizontal. This is your primary size indicator.
Measure around your natural waist — typically 1 inch above your navel. Do not suck in. Our blazer will suppress 6 inches from the finished chest at this point.
Measure across the back from shoulder point to shoulder point (the bony tip of each shoulder). This is the hardest measurement to alter after the fact — fit the shoulder first.
With arm slightly bent, measure from the centre back of your neck, over your shoulder and down to your wrist bone. Add 0.5 inches for shirt cuff to show.
Measure from the top of your collar seam (where your shirt collar meets your shirt) straight down the centre back to where you want the jacket to end — typically mid-knuckle of your thumb.
Measure around the fullest point of your upper arm, typically 1–2 inches below the armpit. Flex naturally, not fully. This ensures comfortable arm movement.
Regular (R): back length under 32 inches. Long (L): back length 32 inches or over, or if you are 6'2" or taller. Long adds 1.5" to body length and 1" to sleeve.
Always size up on chest. The shoulder and chest are the most difficult areas to alter. Waist and body length can be taken in or shortened by a tailor far more easily.
Our blazers are cut with 1¾ inches of ease through the chest — less than a classic American suit, more than a slim cut. The result is a jacket that moves with you, reads clean and tailored in silhouette, and does not pull across the chest or back. The waist is suppressed exactly 6 inches from the chest at every size, giving a defined shape without restriction. The sweep (hem) opens 1½ inches wider than the chest for natural standing and sitting drape.
Match your body chest measurement to the chart below. The finished garment measurements show how the blazer will actually measure on the garment — these are larger than your body to account for ease of movement.

Ease is the difference between your body and the finished garment — it's what allows you to breathe, move, and wear a shirt underneath. Our ease is calibrated for a contemporary silhouette: enough room to function, not enough to look baggy.
If the shoulder seam falls off your shoulder or bites into your neck, no tailor can fix that economically. Fit the shoulder first — everything else is alterable.
Button the jacket. The lapels should lie flat with no X-shaped pulling across the chest. A small horizontal fold means the chest is too tight — size up.
The jacket sleeve should end at your wrist bone, allowing ½" of shirt cuff to show below. If the sleeve is too long, a skilled tailor can shorten from the cuff.
If you find that a Regular fits your chest and shoulders but the body and sleeves are short, try the Long in the same size number. The chest block is identical.
Our 6-inch suppression suits most builds. If you have a very straight torso, the waist may feel slightly shaped. A tailor can let out the side seams easily.
