Dark gray three-quarter sleeve shirt with a back button. The size is 4L, but it has a lot of room. Based on the try-on, it seems like someone who usually wears a 5L size could wear it comfortably. It's new, only tried on, but it has been stored at home, so thank you for your understanding. - Color: Dark gray - Design: Back button - Sleeve length: Three-quarter sleeve - Style: Relaxed silhouette - Neckline: Round neck Thank you for looking.
