Halter TOP is a style of women’s clothing strap that runs from the front of the garment around the back of the neck, and leaving most of the back uncovered. The name comes from livestock halters. The halter style is used with swimsuits, to maximize sun tan exposure on the back and minimize tan lines. It is also used with dresses or shirts, to create a backless dress or top. The neck strap can itself be covered by the wearer’s hair, leaving the impression from behind that nothing is holding the dress or shirt up.
