A blazer is a jacket worn as part of a smart casual or business casual look. Similar to a sport jacket, a blazer is not part of a formal suit, and the terms "sport coat" and "blazer" may be used interchangeably in daily life. A nautical blazer is a double-breasted navy blue jacket with naval-style metal buttons (gold or silver coloured), while rowing/cricket blazers have bright-coloured solid stripes, and a patch on the chest pocket denoting the club or college. Other rowing/cricket blazers featuring a contrasting piping along notched lapels were worn more formally for the presentation of cups or medals. Originally a scarlet jacket worn in club or plain colours when boating or cricketing, the garment gradually lost its connection with sportswear from the 1930s onward to enter classic Ivy style, and the look came to be associated with the lifestyle of wealthy elites in North America and Europe. Blazers can be part of a uniform for employees, pupils of a particular school, members of sports clubs, or sportspeople on a particular team.
