A sleeveless dress is a type of garment that does not have any long, full-length sleeves. It can be worn by women and girls as an alternative to traditional dresses with long or short sleeves. Sleeveless dresses come in various styles such as maxi, midi, knee length, etc., and are made of different fabrics like cotton, silk, chiffon, etc. They can be worn for casual occasions, parties, weddings, or other formal events. The absence of sleeves allows more freedom of movement and makes it a comfortable choice during hot weather.
