Ruches are small pleats or folds of fabric that are used to add volume and texture to clothing. While the term "ruches" is commonly used in the fashion industry, there are several other synonyms that can be used to describe this style element. For example, some may opt to use the term "gathers," which conveys a similar idea of fabric being bunched up in small folds. Alternatively, "frills" or "flounces" can be used to describe ruches that are particularly pronounced and have a more decorative quality. Ultimately, the choice of term will depend on the degree of subtlety and style the designer wishes to convey.
