I purchased this online and tried it on, but the size didn't fit, so I'm putting it up for sale. Please refer to the following HP: A long-sleeved shirt that allows adults to wear it naturally with a sense of composure. A piece that adds a sense of formality to everyday wear that tends to be casual. The relaxed silhouette, with a moderate amount of room throughout, doesn't feel constricting even when all the buttons are closed, creating a clean and calm impression. It achieves both a relaxed feel and a neat impression, realizing the adult balance of "not trying too hard, but not being too casual." The material is 100% cotton typewriter fabric with a crisp feel. It's finished with an exquisite thickness that can be worn year-round, and the fine stitching and shell buttons add a delicate expression and elegance to the simple design. The hem is a rounded shape that looks good tucked in or out, adding softness and movement to the silhouette. Tucks are placed on the back, achieving both a three-dimensional effect and ease of movement. The compact tailoring of the cuffs and collar creates a sophisticated and well-defined impression on the overall relaxed silhouette.
