Single-breasted
From Wikipedia, the free encyclopedia
In clothing, single-breasted refers to a coat or jacket or similar garment having one row of buttons and a narrow overlap of fabric. In contrast, a double-breasted coat has a wider overlap and two parallel rows of buttons.
A single-breasted suit jacket with three or four buttons will elongate a larger upper body and tend to flatter the slim. Double-breasted jackets make the wearer look broad and add bulk.
