The term 'lounging garment' can refer to two different types of clothing: a ROBE and a CAFTAN. A ROBE is a loose-fitting outer garment that is typically worn over nightwear or other clothing. It is usually made of a soft material such as cotton, silk, or velvet. A CAFTAN is a long, loose-fitting garment with long sleeves and an open front. It is usually made of lightweight fabric and is often decorated with embroidery or other embellishments. Both robes and caftans are popular choices for lounging around the house or for wearing to bed.
