★ This material seems suitable for year-round wear. It should be just right even in mid-summer if you're in a room with air conditioning. UNIQLO 80-size striped rompers, a set of two colors: green and white. - Brand: UNIQLO - Size: 80 - Colors: Green/White - Material: 100% Polyester Thank you for viewing. I have kept them stored in a bag. I took them out of the bag for the first time when taking photos. When shipping, I will remove the hanger and outer bag and send only the clothes. (The bag has already been discarded.) I think the material can be worn in all seasons except for mid-summer. Please take a look at my other listings. #chamalist (I have a lot of children's clothes) Please note that I am an amateur in terms of measurements and inspections. Please refrain from purchasing if you are looking for a perfect item. Also, I will compress the clothes for shipping. Please understand that there may be wrinkles. #Uniqlo #UNIQLO #NurserySchool #Nishimatsuya #AkachanHonpo
