Metrosexual is an informal term for a man who exhibits a strong interest in personal grooming, fashion, and an overall cultivated appearance. The term was coined in 1994 by journalist Mark Simpson as a portmanteau of "metropolitan" and "heterosexual."

It describes men, often residing in or near urban centers, who embrace consumer practices stereotypically associated with women or gay men, such as investing in skincare products, designer clothing, and cosmetic treatments. While originally defined by Simpson as potentially fluid in sexual orientation, the term gained popular usage primarily to describe heterosexual men who challenged traditional masculine norms by openly prioritizing their aesthetic presentation and personal indulgence. This aesthetic gained widespread cultural prominence in the late 1990s and 2000s, reflecting shifts in consumer markets and evolving perceptions of masculinity in a post-industrial society.

Metrosexual fashion is characterized by a deliberate attention to clothing, fit, and overall presentation. This extends beyond basic attire to encompass careful coordination of outfits and selection of appropriate footwear for different occasions. While traditional menswear items such as suits, khakis, polo shirts, boat shoes, and dress shoes may be worn, the emphasis is on their cut, quality, and how they contribute to a cultivated appearance. Personal grooming is an integral component of the fashion, involving meticulous care for hair on the head, face, and body, as well as practices like eyebrow shaping or waxing. Accessories such as man bags and silk scarves are incorporated as part of a detailed and considered ensemble. The style reflects a man's investment in his aesthetic, focusing on clean-cut features and a trim, tidy presentation.
