Cotton is the sleepwear fabric of choice for many women; it's hypoallergenic, which is great for sensitive skin. Cotton is also breathable, with moisture-wicking properties to stay dry and comfortable. Now that over 50% of women in the US wear plus sizes (size 14 and above), sleepwear manufacturers offers lots of styles of plus size sleepwear in cotton. Cotton full figure pajamas range from cozy flannel sets to knit and woven separates. Pajama separates are a great option because you can find just the right fit in tops and bottoms. Plus-size cotton nightgowns range from slinky chemises and short gowns to flowing long gowns in petal-soft woven cotton.
