Is GAP's XXS size about the same as a Japanese size M? The size is on the tag, see photo ③. I cut the tag off, but I've never worn it. I haven't washed it either. There are fold wrinkles. Please refrain from purchasing if you are particular about details or are nervous, as it has been stored at home for about 2 years. It's a soft fabric. A simple white T-shirt made of 95% cotton. - Brand: GAP - Model name: MODERN T Color: White Pattern/Design: Plain
