Ready to wear, also known as pret-a-porter, refers to garments that are manufactured and designed to be worn without any additional alterations or customizations. Some synonyms for the term "ready to wear" are "off-the-rack", "store-bought", and "prêt-à-porter". These terms all indicate that the clothing is pre-made and can be directly purchased and worn without the need for any additional tailoring or alterations.
