Sezane Conrad shirt in camel, XS (removing from PM on 1/21!)

I’m the first owner of this shirt and was ready to mark the condition “excellent” BUT when I took a photo in natural light, I noticed what seems to be a water mark (?) somewhere in the upper left of the shirt. Hardly noticeable but happy to add more photos (and give it one more wash). https://luckysweater.com/i/laurennerual
