Proportions — the critical factor in a double-breasted suit
The double-breasted jacket has more surface area to manage than the single-breasted, and proportion errors are correspondingly more visible. The lapel width, the button stance, the depth of the V-opening, the jacket length — all interact differently than they do in a single-breasted garment, and all must be set from your specific measurements and body type.
The jacket must be long enough to cover the seat properly — a DB jacket that is too short looks truncated and uncomfortable. The peaked lapels must have sufficient width to balance the breadth of the overlapping front panels. The button stance must be set so that the jacket closes across your chest without the fabric pulling or the panels gaping.
For men with a fuller chest or a shorter torso, the double-breasted proportions require particular care. We have made DB suits for all body types and will advise at the consultation on what adjustments are needed to make the silhouette work best for you.
When to wear a double-breasted suit
The double-breasted suit is at its best in formal and semi-formal contexts: important business meetings, diplomatic occasions, formal dinners, and weddings as a guest. It is not ideal for creative or casual professional environments where it may read as overdressed. As the most formal of the business suit silhouettes, it works best when the setting calls for formality.
In pinstripe, the DB suit is quintessentially financial and legal — the uniform of the senior banker and the silk QC. In a plain navy or charcoal, it is somewhat more versatile. In a grey or a subtle pattern, it can be worn to a range of occasions. The key rule is to keep the DB suit buttoned when standing — an unfastened double-breasted jacket is a rumpled garment, not a relaxed one.
Cloth and construction for a DB suit
Double-breasted suits reward a medium-to-heavier cloth that holds its shape and drapes with authority. A lightweight tropical worsted, while practical, can look too fluid in the DB format. We recommend a medium worsted at 270–300 gsm for year-round wear in Chennai's air-conditioned environments, or a flannel for the cooler months.
Our DB suits are built to the same canvas standard as our single-breasted jackets — half or full canvas depending on the commission. The additional front panel requires careful canvassing to lie flat and maintain its structure. The lining extends fully through both the jacket's outer and inner panels.
