Which of the following aspects is part of culture and social factors in fashion?

The correct choice highlights the significant influence that culture and social factors have in the realm of fashion. Ethnicity, values, and peer pressure represent the societal context in which fashion operates. They shape individual style preferences, trends, and purchasing behaviors. For instance, ethnic backgrounds can dictate traditional clothing styles and color preferences, while societal values impact the acceptance of certain fashions and body types. Peer pressure also plays a role, as individuals may choose to conform to trends to fit in with their social groups.

In contrast, technical specifications of fabrics fall under the realm of material science and textile technology, focusing on the functional aspects rather than cultural implications. Celebrity endorsements do influence fashion trends, primarily through marketing practices and brand visibility, but they do not encapsulate the deeper cultural and social factors that shape individual identities and group dynamics. Online shopping habits pertain to consumer behavior and technological advancements in retail rather than cultural aspects influencing fashion choices. Each of these alternatives reiterates different components of the fashion industry, but they do not embody the essence of culture and social factors as effectively as the correct choice does.
