Some historians observe the frequently changing clothing styles as a distinctively Western habit among urban populations.[dubious – discuss] Changes in costume often at times of economic or social change (such as in ancient Rome), but then a long period without large changes followed. In 8th century Cordoba, Spain, Ziryab (a famous musician of that time) is said to have introduced sophisticated clothing styles based on seasonal and daily timings from his native Baghdad and his own inspiration.
The beginnings of the habit in Europe of continual and increasingly rapid change in styles can be fairly reliably dated to the middle of the 14th century, to which historians including James Laver and Fernand Braudel date the start of Western fashion in clothing.[2][3] The most dramatic manifestation was a sudden drastic shortening and tightening of the male over-garment, from calf-length to barely covering the buttocks, sometimes accompanied with stuffing on the chest to look bigger. This created the distinctive Western male outline of a tailored top worn over leggings or trousers.
