This is a UNIQLO flannel shirt. It's a blue block check shirt, and the size is M. The fit is about a typical UNIQLO M. I bought it, but honestly, I barely remember wearing it. It has been stored at home and is a used item, so please refrain from purchasing if you are looking for something new or perfect. I am also listing it on other flea market sites, so there is a possibility that it may be suddenly removed from listing. Thank you for your consideration.
