Pajamas, once mainly matched sets of sleep shirt and long loose pants, have branched out into everything from snug cropped capris with a tank top to shorts with camis, a chemise, and tee-shirt style tops. The classic favorites are still popular, too, from lightweight cotton lawn or poplin to jersey, microfiber and heavy flannel. Once always sold in sets, pajamas are often now sold as separates, allowing you to mix and match.
Regardless of style, cotton pajamas may be the most popular of all. Cotton is a natural fiber, breathable and hypoallergenic. Whether knit or woven, cotton can also be fabricated in different weights and finishes. Some cotton pajamas are brushed for extra softness. Cold weather styles are often 100% cotton flannel. This versatile fiber may also be a lightweight woven, like cotton lawn, airy and almost sheer. Long, short, cozy or lightweight, cotton pajamas are available in so many styles, they've got you covered year round.
