The world’s very first formal gown was the mantua, which was introduced in the early 18th century. With a thick overskirt, a petticoat, and a long train that was often allowed to trail, the mantua was a heavy and uncomfortable gown. But because it was the most elaborate dress of its age, it was worn to all the best parties, especially those at Court, in the presence of a monarch. Formalwear for females got evermore elaborate with dresses like the sack-back and the ball gown. It was not until the 19th century that the term evening gown was used to describe a dress that women could actually comfortably wear. These evening gowns ranged from ornate floor-length numbers with flounces and puffy sleeves to off-the shoulder dresses with low necklines and no sleeves. Even the hemlines rose a bit from floor to ankle length. The greatest leap forward, or backward, depending on your perspective, occurred during the 1920s. It was the age of the flapper and girls just wanted to have fun. They wanted to move and dance and have a good time without being encumbered by heavy, elaborate dresses. Fashion designers were quick to accommodate them with shorter, simpler gowns that used less fabric and fewer layers.

It was at this time that the arbiter elegantiarum finally accepted party dresses as formalwear. Where are we now?
