I only tried it on once, over my clothes. I'm selling it because it was a little too big for me. Due to the lighting in my room, the color looks different, so I'm using photos from Uniqlo. It's a non-button-down shirt. - Color: Light Blue - Size: XL - Size details: Length 80 cm, Width 88 cm, Shoulder width 52 cm, Sleeve length 64 cm Thank you for looking.
