A bachelorette party or hen night is a party held for a woman who will soon be married. While Beth Montemurro concludes that the bachelorette party is modelled after the centuries-old stag night in the US, which is itself historically a dinner given by the bridegroom to his friends shortly before his wedding, Sheila Young argues that its British counterpart evolved from a number of earlier pre-wedding traditions for women whose origins are obscure but which have been around for at least a century in factories and offices across the UK.
