Oligopoly does not ? Does it include fashion sector

Regarding the fashion sector:
Yes, the fashion sector can exhibit characteristics of an oligopoly, especially in certain segments. For example, the high-end designer fashion market or the mass-market fast fashion industry can be dominated by a few major global brands or corporations. These firms have significant market power, high brand recognition, and often control a large portion of the market share. Barriers to entry can be high due to the need for significant capital investment in design, manufacturing, marketing, and distribution, as well as strong brand loyalty.

However, the fashion sector is very broad. Other parts of the fashion market, like independent boutiques or niche apparel, might operate under monopolistic competition or even closer to perfect competition if there are many small sellers offering similar products with low barriers to entry.
