There are three basic forms of lapels: notched, peaked, and shawl. The notched lapel double-breasted jacket is a rare setting. This was the first type of lapel to appear.
In the late 1920s and 1930s, the single breasted peaked lapel jacket was considered a very stylish design. The feature was carried into day clothing by the increasing popularity of the peaked dinner jacket.
