A bachelorette party, hen(s) party, hen(s) night or hen(s) do, is a party held for a woman who is about to get married. The terms hen party, hen do or hen night are used in the United Kingdom and Ireland, while the terms hens party or hens night are common in Australia and New Zealand, and the term bachelorette party is common in the United States and Canada. The terms stagette and hen party are sometimes used in Canada. It may also be referred to as a girls' night out or kitchen tea (South Africa in particular) or other terms in other English-speaking countries.
The bachelorette party is modeled after the bachelor party, which is itself historically a dinner given by the bridegroom to his friends shortly before his wedding. Despite its reputation as "a sodden farewell to bachelor days" or "an evening of debauchery," a bachelorette's party is simply a party, given in honor of the bride-to-be, in the style that is common to that social circle.
Prior to its usage as a term for a pre wedding party "hen party" was used in the United States as a general term for an all female gathering usually held at a hostess's residence. In 1897, The Deseret News noted that "hen party" was a "time honored idea that tea and chitchats, gossip smart hats, constitute the necessary adjuncts to these particular gatherings". In 1940 Eleanor Roosevelt was described as hosting a Christmas time "hen" party for cabinet wives and "ladies of the press".
The bachelorette party is consciously modelled after the centuries-old bachelor's party, which is itself historically a dinner given by the bridegroom to his friends shortly before his wedding.
Although the practice of giving a party to honour the bride-to-be goes back for centuries, in its modern form, the bachelorette party may have begun during the sexual revolution of the 1960s. It was uncommon until at least the mid-1980s, and the first book on planning bachelorette parties wasn't published until 1998. Its cultural significance is largely tied to concepts of gender equality.
