裁缝 (cái féng) literally combines 裁 (cái), meaning 'to cut' — as in cutting fabric to size — and 缝 (féng), meaning 'to sew'. Together, they refer to a person who measures, cuts, and stitches clothing, i.e., a tailor. Historically, tailors were essential in Chinese communities, often working in small shops or visiting homes to make or alter garments like qipaos, suits, or traditional robes. Today, while mass-produced clothing is common, 裁缝 still denotes skilled garment makers, especially those offering custom fittings or repairs.

The word functions exclusively as a noun referring to the person, not the act or profession as an abstract concept (for which you’d use terms like 裁缝行业 or 服装制作). It’s neutral in register — appropriate in both spoken and written contexts — and commonly appears in phrases like 老裁缝 (experienced tailor) or 找裁缝改衣服 (take clothes to a tailor for alterations). Unlike English 'tailor', 裁缝 has no verb form in modern usage.
