Boglioli collarless button up long sleeve shirt. SIZE 43/17 - think of it between a L and XL. 100% cotton and tailored fit. Olive green with a subtle pattern (zoom in to see) and in incredible condition. Boglioli makes incredibly high quality Italian clothing - this will be a great summer casual look. Open to offers - but retail on this was almost $400 - just ask that you be reasonable. :) Measurements in photos.
