The terms "fashionable" and "unfashionable" were employed to
describe whether someone or something fits in with the current or even
not so current, popular mode of expression. However, more so in the
modern era items termed 'not so current' may indeed fit into the term
'Retro.' Retro fashion allows rule shifts, such as 'old is suddenly
new,' thus fashionable. The term "fashion" is frequently used in a
positive sense, as a synonym for glamour, beauty and style. In this
sense, fashions are a sort of communal art, through which a culture
examines its notions of beauty and goodness. The term "fashion" is also
sometimes used in a negative sense, as a synonym for fads and trends,
and materialism. A number of cities are recognized as global fashion
centers and are recognized for their fashion weeks, where designers
exhibit their new clothing collections to audiences. These cities are
Paris, Milan, New York, and London. Other cities, mainly Los Angeles,
Berlin, Tokyo, Rome, Miami, Hong Kong, São Paulo, Sydney,
Barcelona, Amsterdam, Madrid, Mumbai, Vienna, Moscow, New Delhi and
Dubai also hold fashion weeks and are better recognized every year.
