A DOUBLET is a type of body garment that was popular in the 15th and 16th centuries. It is a close-fitting, hip-length jacket with a short skirt, often made of velvet or other luxurious fabrics. It was typically worn over a shirt and hose, and was often decorated with embroidery or fur trim. The DOUBLET was an important part of men's fashion during the Renaissance period, and was often seen in portraits of the time.
