Clothes rhymes with "nose," and your nose is one of the few body parts you don't often cover with clothes. Pants, shirts, and coats are types of clothes.
Clothes comes from the word cloth — it's true: Most clothes are made of cloth, or fabric. Whether you wear suits, uniforms, or jeans, clothes cover the body, just as bed clothes is a term for the sheets and blankets that cover a bed. You can show your style with the clothes you wear, or you might just throw on whatever clothes are clean (or sort of clean) and available.
