A dress suit is typically associated with formal events and occasions, where one is required to dress elegantly. However, there are several other terms that can be used instead of the term 'dress suit'. One such term is 'tuxedo', which is a formal suit worn by men. It is often black with a satin lapel and worn with a bowtie. Another term that can be used interchangeably with 'dress suit' is 'formal attire'. This term includes a range of formal dress codes, including black-tie, white-tie, and semi-formal. Additionally, a 'dinner jacket', 'evening suit', or 'dressy suit' can also be used as synonyms for a dress suit.
