Rails "Carter" Chambray Shirt in Dark Vintage Wash, S

Button down shirt in medium blue chambray (see photos for materials and composition). The best feature of this piece is how lightweight the fabric is -- it breathes and hangs better than most similar styles. Top has button cuffs, chest pockets, and a slightly gathered yoke. Lyocell. Marked size S but like many Rails styles, IMO it runs maybe a half size smaller than that. I think this style, which is meant to look relaxed, would be most flattering on someone who typically wears an XS. Pit to pit measures about 18.5". Pre-loved but in excellent condition. Only listing because it turns out Rails sleeves are on the narrow side for my preferences.
