formal Japanese male attire with family crest
A set consisting of a haori coat bearing the family crest and a hakama, worn on ceremonial occasions such as weddings.
See also: はおりはかま
結婚式では、新郎の父親が紋付羽織袴を着ることが多い。
At weddings, the groom's father often wears a formal crested haori and hakama.
Refers to the haori and hakama combination without the family crest; 紋付羽織袴 specifically includes the crest.
Compound of 紋付 (crested) + 羽織 (haori coat) + 袴 (hakama). The exact historical derivation is uncertain, but the term describes the formal attire set.
