Suspenders refer to trousers with shoulder straps at the waist. There are only two straps connecting the suspenders in pants, but in overalls and modern fashion, there are many chest stickers. The name of modern trousers, also known as "rice trousers" or "overalls", is to add a chest protector (commonly known as rice trousers) to ordinary trousers or shorts, and tie a strap instead of a belt, hence the name.
