Late Middle Ages: Gothic Period (14th and 15th Century)
Many historians point to the 14th century as the point at which changes in fashion began. About 1340, styles for men changed markedly and a number of new garments came into use, among them the cote-hardie and houppeland (my favorite word in fashion history, houppeland!)
The wide, funnel sleeves of this Alexander McQueen gown reminds me of the sleeves of these garments.
