Although it's a size M, I, who usually wear L, was able to wear it comfortably and coolly in the spring and summer. The design has an open back, so it was cool in the summer. (You can adjust with a tank top) It has pockets on both sides. Because of the simple color and design, it seems like you can change it up with various innerwear! The fabric is smooth like linen. *There was a small stain on the fourth photo. Please refrain from purchasing if you are sensitive to imperfections or seek perfection. I have many other items for sale, so feel free to comment if you'd like to bundle them together＾＾
