A "fancy dress party" is a type of event where attendees dress up in costumes and accessories that reflect a theme or era. Synonyms for this term can include "costume party," "themed party," "masquerade ball," or "dress-up party." Each of these terms describes similar events, but with slightly different connotations or expectations. A costume party may have a specific costume theme, such as superheroes or historical figures, while a masquerade ball typically involves elaborate masks and formal attire. A themed party may have a broader theme, such as the 1980s or a specific color scheme. Whatever the term used, these parties offer a chance to dress up, have fun, and escape reality for a little while.
