Haute couture (French for 'high sewing' or 'high dressmaking'; IPA: [ˌoːt kuˈtyʁ]) refers to the creation of exclusive fashions. It is a common term for custom-fitted clothing as produced primarily in Paris but also in other fashion capitals such as New York, London, and Milan.

A fashion trend refers to the prevailing style, preference, or popular choice of clothing, accessories, or overall appearance that is embraced by a significant number of people within a specific time period. It represents the collective shift in tastes, aesthetics, and consumer preferences within the fashion industry.

The 20th century truly saw the greatest changes in fashion, from corsets and petticoats to leather miniskirts, this century was full of change and diversity. No decade was the same and each had its own influences. I'm not sure any century will see such a change in fashion ever again.
