Brioni designer button up dress shirt

Brioni designer dress shirt size 16. There is small stain shown in the fourth photo on the outside of the collar but hardly noticeable and a very tiny one on the inside(which can’t be seen when worn since it’s the inside of the collar). Dry cleaning will likely get the stain out fairly easily, I just haven’t tried. These dress shirts retain for $700-$900 as shown in the second photo, I’m selling it at a fraction of the price due to the small stain and because the interior label came off. The shirt buttons feature Brioni label stamping and it is made in Italy
