Formal trousers

Trousers for formal day attire

Formal trousers, also known as formal striped trousers or colloquially spongebag trousers, are grey striped or patterned formal trousers for day attire in traditional Western dress code, primarily associated with formal morning dress or secondly its semi-formal equivalent black lounge suit. Traditionally made from heavy wool ranging from worsted, melton to partial twill weave, the pattern is most often of a muted design in stripes of black, silver, white and charcoal grey in various combinations. In addition, formal trousers may also come in check patterns, such as houndstooth check, or plaids, although these variants are widely considered as not the most formal.
