For a jacket to be the right size, three points are crucial: the shoulder seam must fall exactly at the end of the shoulder, the length must cover the belt without going past the buttocks, and the chest measurement must allow for buttoning without pulling. These markers are enough to eliminate most poor choices before even entering a fitting room.
The shoulder: the criterion that cannot be rectified
The shoulder seam — the joining line between the body of the jacket and the sleeve — is the only point of the jacket that cannot be easily adjusted by a tailor. It is therefore the first criterion to check.
When the jacket is worn, this seam must be located exactly at the end of the shoulder. Neither further in (the jacket pulls, the armhole compresses), nor further out (the sleeve head falls on the arm, the silhouette sags).
A shift of one to two centimeters inwards or outwards radically changes the overall look. This is often where a well-chosen jacket is distinguished from one that is merely worn.
Length: a matter of proportion
The ideal length of a jacket depends on the model, but some markers remain constant:
- The jacket must cover the entire circumference of the pant belt.
- The bottom of the jacket is generally at mid-buttock, without going past the crotch of the pants.
- With arms hanging by the body, the hand should reach the bottom of the jacket — a common reference, but variable depending on the cut.
A jacket that is too short exposes the shirt and deconstructs the silhouette. Too long, it visually shortens and weighs down the overall look. The Benjamin Jezequel collection jackets are designed for balanced proportions, requiring no correction for the vast majority of body types.
Chest circumference and ease
Standing, jacket buttoned, slide a flat hand between the jacket and your torso. It should pass without forcing, and without leaving excessive space. This is what is called functional ease: the jacket follows movement without restricting.
If the fabric creates horizontal folds under the top button or pulls at the chest, the jacket is too small. If vertical folds fall freely from the shoulder, it is probably too large.
Summary table: control points
| Control Point | What to Observe | Sign that it's not right |
|---|---|---|
| Shoulder seam | Falls at the end of the shoulder | Offset inwards or outwards |
| Length | Covers the belt, stops at mid-buttock | Too short (shirt visible) or too long |
| Chest circumference | A flat hand passes without forcing | Horizontal folds or fabric pulling |
| Sleeve length | Allows 1 to 1.5 cm of shirt to show | Sleeve too long or too short |
| Collar | Lies flat on the shoulders, no gap at the back | Collar lifting or pulling back |
Sleeve length: the adjustment that can be rectified
Unlike the shoulder, sleeve length is one of the few points that can be easily modified by a tailor. The most common convention: the jacket sleeve should show about one to one and a half centimeters of shirt at the wrist. It's a detail, but it contributes to the overall finish.
If a jacket fits you perfectly on all other criteria but the sleeves are too long, do not reject it for this reason alone. Shortening sleeves remains a common and inexpensive alteration.
Sitting and in motion: the often-forgotten test
A jacket may seem impeccable when standing but become restrictive as soon as you sit down or raise your arms. In the fitting room, take the time to:
- Sit down: the collar should not lift at the back, the shoulders should not pull.
- Raise your arms to shoulder height: the jacket may ride up slightly, which is normal, but it should not restrict movement.
- Button and unbutton: the gesture should be fluid, without the fabric deforming.
If you are buying online, systematically check the size guide and compare it with your actual measurements. To explore available cuts, the Benjamin Jezequel jacket collection indicates reference measurements for each model.
Frequently Asked Questions
Can a jacket be tailored?
Yes, for most points: sleeve length, waist tailoring, overall length. However, shoulders cannot be easily altered — which is why this criterion takes precedence over all others when purchasing.
What is the difference between a slim fit and a regular fit for size?
A slim fit is tailored at the waist and chest, with little extra ease. A regular fit offers more space and suits more body types. Both can be the right size: the choice depends on the desired comfort and use.
How to take your measurements to order a jacket online?
Three measurements are sufficient for most size guides: chest circumference (under the armpits, at the widest part), waist circumference, and shoulder width (from one end of the shoulder to the other, across the back). Measure over a thin t-shirt, not over a jacket already worn.
