1. When choosing pajamas, one of the most important details is the fabric. The most popular materials for women's pajamas are cotton and silk, because of their softness and breathability.
2. Nylon and synthetic fabrics make the best pajamas for those living in colder climates, because these materials tend to trap in body heat. However, newly patented moisture wicking polyester materials have recently been developed.
3. The most comfortable type of pajamas are loose fitting with as few embellishments as possible, as they don't constrain you or bind the skin, and won't irritate you with extra fabrics or flashy buttons.
4. Always keep in mind who you're shopping for if you're purchasing women's pajamas as a gift. You probably won't want to buy your sister the same pajamas that you'll buy your girlfriend.
5. If you like sleeping in a cold room, buy warmer pajamas, but if you're a cover-kicker who gets warm in your sleep, try some loose-fitting, lightweight PJs.
