Sleeveless tunics are a type of clothing that have been around for centuries. They are usually loose-fitting garments that hang from the shoulders and have no sleeves. Tabards, which are also sleeveless tunics, are a type of garment that was popular in the Middle Ages and Renaissance periods. They were typically worn over armor or other clothing and had a slit in the front and back to allow for ease of movement. Tabards were often decorated with heraldic symbols and were used to identify knights and other members of the nobility.
