The shape of the front of the suit is particularly affected by the way the suit buttons. The two main cuts consist firstly of double-breasted suits, a conservative design with two vertical rows of buttons, spanned by a large overlap of the left and right sides. Usually double-breasted suits have one hole on each lapel (with a flower just on the lef).
Double-breasted jackets usually have peaked lapels. Shawl lapels are a style derived from the Victorian informal evening wear, and as such are not normally seen on suit jackets except for dinner suits.In the 1980s, double-breasted suits with notched lapels were popular among the Power suit and the New Wave style.
