This floral blouse was purchased in the US. The size is listed as S, but it's a US size, so it would likely fit like a Japanese M. It has vibrant colors that are hard to find in Japan. The back is lace, showing a tasteful amount of skin and making it very cute. I wore it once while I was there, and it has been stored at home since then. I do not have any pets or smoke in my home. Please feel free to ask if you have any questions.
