Single-breasted suits and double-breasted suits represent two major styles of suits. Single-breasted suits can be divided into single-breasted lapels and single-breasted lapels, while double-breasted suits only have lapels. The most essential difference between single-breasted and double-breasted buttons lies in the difference of the overall effect brought by the difference of the front. First, the overlapping lapels of double-breasted buttons make the V-zone of neckline smaller than that of single-breasted buttons. Secondly, the double-breasted hem is right-angled, while the single-breasted hem is curved. The difference of hem directly leads to the difference of visual effect. The same special-shaped single-breasted suit and double-breasted suit, the double-breasted suit is visually longer than the single-breasted suit.
Furthermore, double-breasted suits are not as relaxed as single-breasted suits because of their overlapping front and poor bust and waist size. From the upper body visual effects of single-breasted and double-breasted suits, the line sense of single-breasted suits is more obvious than that of double-breasted suits.
