Fabiana Filippi Button up belt gray cardigan top

Fabiana Filippi Button up belt gray cardigan. This cardigan is glorious. I mean it, glorious. Cozy. Gorgeous cut and incredible faux white button down shirt effect. The size is listed as US XL. This is a lie. It is more closely a size EU 40-42. Or a US sz S-M(8). My guess is it shrunk! Please drop a comment if you need measurements🙏 Belt is near new shape.
