In short
A single-breasted suit has one row of buttons and is more versatile and easier to wear. A double-breasted suit has two rows, is more formal, and needs to be worn fastened to keep its shape.
The front of a jacket changes the whole character of a suit. Neither is better, but they suit different people and occasions.
Single-breasted
- One or two buttons, notch or peak lapels, side vents.
- Can be worn open or closed; more forgiving of body shape.
- The default for business, weddings and first suits.
Double-breasted
- Six or four buttons, peak lapels, often no vent.
- Should be worn fastened; the wrap needs a defined waist.
- More formal and adds presence; best on slim to average builds.
Choosing between them
If you need one suit, make it single-breasted. If you already own navy and charcoal and want something with authority, a double-breasted chalk stripe or navy hopsack is a strong next step.
Fit notes
Double-breasted jackets must be cut closer through the waist; a loose one looks shapeless. Single-breasted jackets are more tolerant of a little extra room, which is why they work for a wider range of builds.
