Regarding the 6th image, it's from a Korean MUJI website that came up when I searched for what appears to be the product number listed on the collar, so please consider it as a reference only, as it's not definitive. This shirt is made of a thick material that holds its shape quite well, creating a three-dimensional silhouette. It can be worn open or closed. I believe I wore it about twice and then stored it. Due to the nature of the photos, the color may appear faded, but I don't perceive any fading when looking at it in person. There are no noticeable stains or scratches, and it's in good condition. It's still perfectly wearable. - Color: Navy - Design: Collarless, Stand Collar - Style: Casual - Material: Cotton blend Thank you for looking.
