Thank you very much for viewing my product from among many others. This is a UNIQLO bear ear all-in-one. The size is 70, which is a bit large. Unless you layer a lot underneath, I think it will fit like an 80. My daughter, who is of average build, was able to wear it until she was about a year and a half old. I liked wearing it, but there is no noticeable damage, and you can still wear it. Recent products have buttons, fleece, quilting on the zipper, making it easy to use, warm, and cute.
