A fancy dress party (British English) or a costume party (American English), mainly in contemporary Western culture, is a type of party where guests dress up in a costume.

The origins of fancy dress parties in the UK can in some respects be traced to masked balls of the 18th century period, although Fancy Dress parties of the modern kind are a largely Victorian conception^{[citation needed]} expanded upon by the Edwardians.

Notable amongst early events in the 20th century was the Chelsea Arts ball. Such events were often elaborate affairs and for the most part confined to those with considerable means.^{[citation needed]}

Amongst the general population, costume parties also occurred with increasing frequency from the late 1940s onward, although for the most part the costumes were simple affairs until the mid 1970s. Prior to 'cheap' costume imports from the Far East (late 1990s)^{[citation needed]} most costumes were either hired, or home constructed. Retail purchased costumes is in respect of the UK, a largely modern phenomenon (late 1990s onward) although 'accessory' items had been available for some time.^{[citation needed]}
