A crop top (or a belly shirt, tummy top, or half shirt) is a kind of shirt that is mostly for women. Crop tops do not cover all of the middle section of the wearer's body. A person wearing a crop top will have part of their belly and back showing. There are many kinds of crop tops, and most styles show the wearer's belly button. Other styles can show the wearer's waist, or the bottom of their ribs.
