KK: /ˈpɪnəˌfɔr/
A type of clothing that is sleeveless and often worn over a dress or as a dress itself, commonly associated with young girls.
She wore a cute pinafore over her blouse and skirt.
Pinafore → The word is formed from "pin" (from Middle English *pinne*, meaning a fastening or clasp) and "a fore" (from the phrase meaning at the front). A pinafore is a garment that fastens at the front, typically worn over clothing.
Think of a 'pin' that fastens something 'at the front' — that's how a pinafore is worn over other clothes.
