1200–1300 in European fashion

Costume during the thirteenth century in Europe was relatively simple in its shapes, rich in colour for both men and women, and quite uniform across the Roman Catholic world as the Gothic style started its spread all over Europe in dress, architecture, and other arts.

Male and female clothing became remarkably similar, with many men's garments differing substantially from women's dress only in hem length, with the fanned sleeves common in the previous century vanishing from the latter and tightly buttoned sleeves becoming common. While most items of clothing, especially outside the wealthier classes, remained by comparison little changed from three or four centuries earlier, the more tightly shaped cuts that had been introduced in the preceding century continued to evolve in commoners' fashion too, with the imitation of nobles' clothing beginning among the developing burgher class that would become prominent in following centuries.

The century saw great progress in the dyeing and working of wool, which was by far the most important material for outerwear. For the rich and fashionable, vibrant colour and rare fabrics such as silk from the silkworm were ubiquitous. Silk started to be produced in Europe in greater quantity than before, with silk embroidery seeing notable developments away from the style of Chinese silk that had been imported earlier; these would continue into unique European styles of silkwork in the 14th century.

The most common dyes remained shades of red, notably carmine, and basic yellows and greens. A lapis lazuli-dyed, intense blue became very fashionable, being adopted by the Kings of France as their heraldic colour.
