A type of clothing that does not have sleeves.
She wore a sleeveless dress to the party.
Sleeveless → It is formed from "sleeve" (from Old English *slēfa*, meaning the part of a garment that covers the arm) and "-less" (meaning without). The word "sleeveless" means without sleeves, referring to a garment that does not have arm coverings.
Think of a garment that is 'without' ('-less') 'sleeves' — that's why sleeveless means it has no sleeves.
