Yellowing on the collar (photos 6, 7, and 8). Photo 9 shows how the yellowing looks from the back when the collar is folded. There is slight yellowing visible on the fold. The cuffs are clean with no yellowing (photos 10, 11, and 12). There is a pattern, though it's not easily noticeable from a distance (photo 4). Regarding the collar yellowing, it's not very noticeable when worn, but I've tried to photograph it as accurately as possible, so please check the photos before considering a purchase. It was worn for only one season and stored at home. The fabric is not flimsy; it's firm and sturdy. The collar shape is stylish, and it would look great paired with a cardigan or sweater this time of year. The tag says XL, but it's not that large. So, it should fit someone who usually wears an X. There is no odor. Thank you for looking.
