These cool pajamas from Renoma are made of shirred material, ideal for a hot summer. Made of 99% cotton, the material is light and very cool. These are Amour, high-quality pajamas made by Arakawa. I wear a different color, and I wash them every day and wear the same ones to bed every night. Even on rainy days, or days when I have to dry them indoors, they dry without fail. Honestly, I can't do without them (lol). This summer, which is difficult to sleep in, they might lead you to a good night's sleep. Size M Please be sure to check my profile. These are items stored at home and are being sold by an amateur, so they are not perfect. Please refrain from purchasing if you are concerned. I may have overlooked some fraying or stains, but please understand this before purchasing. #GoodSleepPajamas #ShirredMaterial #Cool #Renoma #renoma #Pajamas #Women's #Women'sBedding #Nightwear #RelaxingWear #RelaxWear #Bedding #CoolBedding #ComfortablePajamas #Cool Color...Blue系 (Blue-based) Sleeve Length...Short Sleeve Season...Spring, Summer, Autumn
