Components

radical
clothing (left-side form of 衣)
Clothing radical on the left — the left-side form of . originally meant 'a quilted cover, a blanket' (cloth that covers the body), and from 'covered by' developed into the modern passive marker. Same radical heads shirt, skirt, bag, sleeve — the textile family.
phonetic
skin; hide
Right side supplies the sound: pí → bèi with the regular Old Chinese p/b alternation. Carries faint semantic weight — a covers the body like a second (skin). Same phonetic also gives (drape over), (break), (wave) — a wide labial family.
