A sleeveless top is a type of clothing that does not have any long, full-length arms attached to it. It refers to shirts or blouses that are designed without sleeves, leaving only the upper part of the torso exposed. Sleeveless tops can be worn in warm weather and provide comfort and freedom of movement. They come in various styles such as tanks, camisoles, halters, etc., and can be made from different fabrics like cotton, linen or silk.
