Made from rare 600-thread-count 100% Egyptian cotton, these are the most opulent women's cotton pajamas available. Comprising less than one percent of the world's total cotton output, Egyptian cotton is legendary for its softness and fibers that are twice as long as other varieties, allowing it to be woven into extraordinarily fine yarn. As a result, these cotton pajamas are warmer and more durable than those with lower thread counts, and as smooth and lustrous as silk. The pajama top has four genuine mother-of-pearl buttons and the bottom has a drawstring and elastic waist; both have French seams, double-seamed at the wrist, waist, and ankle to ensure lasting durability. The pajamas actually become softer with each successive machine wash. Lilac. Women's sizes S (2-4), M (6-8), L (10-12), XL (14-16).
