This is an OVERCOAT from MAATEE&SONS. The COLOR is GRAYSHAMBRAY, and the SIZE is 4. I purchased it from the select shop Linn in Nakameguro. I believe SIZE 4 is rare, as it's only sold at Linn. Thank you. COTTON GRAYSHAMBRAY Overwhelming gray chambray. The aura increases as it's worn and the material ages. The slick touch from the weft yarn and the unevenness of the warp yarn. It looks like vintage clothing, but the material is incredibly good. The color is also good. The quality of silk, a smooth, slick feel. SIZE 4: Length 115cm / Width 70cm / Sleeve Length 91cm
