This is a new with tags, never worn, gorgeous oversized button down in 100% silk. Because this is the Max shirt from Sézane, it means that it is cut a bit bigger than their tomboy shirt. For a more fitted look, size down from your regular size. The size number on the shirt says 38, which is what shows up when you order a size 10 from Sézane. Chest measurement taken laying flat: 22.5 inches Length taken flat: 27 inches The shirt also has a spare button sewn inside the washing instructions tag. Feel free to make me an offer!
