Pajamas are usually made from soft fabrics like cotton, flannel, or silk, providing warmth and comfort during rest. PJs can also reflect personal style, featuring different colors, patterns, and designs. Many people enjoy wearing PJs for relaxation, and they are often associated with cozy activities like reading or watching movies. Some brands even create themed pajamas for holidays or special occasions, adding a fun element to bedtime attire.
