Blazer

A character with this trait wears or has worn a blazer.

A blazer is a type of jacket resembling a suit coat, but cut more casually. Blazers often have naval-style metal buttons to reflect their historic association as jackets worn by boating club members.

Blazers are often part of a uniform that denotes, for example, an airline's employees, students of a particular school, members of yachting and rowing clubs, and athletes on a particular team.
