fashion in the 15th century

In 15th entury Europe, fashion involved a series of extremes and extravagances, from the voluminous gowns called houppelandes with sweeping floor-length sleeves to the revealing doublets and hose of Renaissance Italy. Hats, hoods, and other headdresses assumed increasing importance, and were swagged, draped, jewelled, and feathered.
As Europe continued to grow, the urban middle classes, skilled workers, began to wear more complex clothes, at a distance, the fashions set by the elites. National variations in clothing seem on the whole to have increased over the 15th century
Women's fashions of the 15th century consisted mostly of a long gown, usually with sleeves, worn over a kirtle or undergown, with a linen chemise or smock worn next to the skin. The long-waisted silhouette of the previous period was replaced by a high-waisted style with fullness over the belly, often confined by a belt. The wide, shallow scooped neckline was replaced by a V-neck, often cut low enough to reveal the decorated front of the kirtle beneath.
