A blazer is a type of jacket resembling a suit jacket, but cut more casually. A blazer is generally distinguished from a sport coat as a more formal garment and tailored from solid colour fabrics. Blazers often have naval-style metal buttons to reflect their origin as jackets worn by boating club members. A blazer's cloth is usually durable, as it is intended as outdoor wear.

In schools, this badge may vary according to the pupil's standing in the school: being a member of the junior or senior school, being a prefect, or having been awarded colours in recognition of particular achievement in some academic or sporting field.
