Renaissance courts were in constant flux as nobles moved in and out of a ruler's household. 7 These developments had an enormous impact on the material culture of the age, which witnessed an unrestrained accumulation of goods. 8 Luxury objects and fashionable garments were valuable assets that set elite families apart from the working poor. 9 Over two centuries of great economic and demographic expansion (ca. 1450-ca. 1650), new patterns of production, merchandizing, and consumption in the creation and dissemination of paintings, decorative ornaments, tapestries, and illuminated manuscripts, and the design and production of clothing significantly changed what clothing signified to individuals, within their respective communities and across the Continent. 10 Clothing assumed a central position in this "world in motion" as it developed into complex social systems of dress: textiles and trims were acquired in local, urban, and international markets, and individual identities were formed no longer solely according to regional, economic, and political dictates but also in accordance with social, aesthetic, and industrialized processes that embraced both global techniques and individual preferences. Clothing for the upper echelons of society was made of intricate textile weaves and patterns. 11 Aristocrats sought social differentiation through dress codes and elaborate spending because social status depended not only on luxurious cloth but on how cloth was fashioned into garments that followed precise, often individual guidelines. 12 Artifacts or worldly possessions and luxurious clothing, however, were separate and distinct from the household items that constituted instead an individual's patrimony and investment for one's heirs. 13 On account of fluctuations in the amount of textiles produced in the early modern period and "above all, because the values extolling the new, and the need for replacement to keep pace with fashion were late to gain precedence over those of conservation and tradition," as Laurence Fontaine argues, clothing no longer served the purpose of "storing value," given the growing popularity of cheap materials and secondhand markets where clothes could be bought. 14 Once clothing became integrated into a system of social codes, it was subject to ongoing political, economic, religious, and social change. The expansion of Europe meant an unprecedented increase in two-way cultural exchanges of knowledge which Europeans carried into unknown areas around the globe-from West Africa to India, China, and Japan in the east, to the Americas in the west. New settlers brought with them the most recent technological inventions for producing cloth.
