Aiayu signature PYJAMAS POPLIN is a beloved customer favorite. This soft and breathable sleep-set is comprised of two versatile pieces: an attractive button-down shirt and matching pants. Made from crisp organic cotton poplin, this set is the perfect combination of cool, casual, and comfortable. The shirt is oversized with a flattering V-neck and button closure front. The pants have a relaxed fit with a slightly cropped length and an elastic drawstring waist.
