In the 16th century, national differences were at their most pronounced. Ten 16th century portraits of German or Italian gentlemen may show ten entirely different hats. Albrecht Dürer illustrated the differences in his actual (or composite) contrast of Nuremberg and Venetian fashions at the close of the 15th century (illustration, right). The "Spanish style" of the late 16th century began the move back to synchronicity among upper-class Europeans, and after a struggle in the mid-17th century, French styles decisively took over leadership, a process completed in the 18th century.
Though textile colors and patterns changed from year to year, the cut of a gentleman's coat and the length of his waistcoat, or the pattern to which a lady's dress was cut, changed more slowly. Men's fashions were largely derived from military models, and changes in a European male Silhouette were galvanized in theaters of European war where gentleman officers had opportunities to make notes of foreign styles such as the "Steinkirk" cravat or necktie.
