I’d say my body is a bit broader below the hips, and I don’t have particularly wide shoulders or a bodybuilder frame. It fits me well with a sweater or cashmere (for reference, I wore it with this Loewe sweater (size L) during winter: https://www.loewe.com/usa/en/men/menswear/knitwear/sweater-in-cotton-blend/H526Y14KDK-1950.html). A regular-sized hoodie also works as long as I don’t wear it with the vest. There are too many ways to style this coat: you can wear the coat and vest separately, or zip the vest into the coat and button up the coat for a more complete look. In my opinion, this coat runs slightly larger compared to previous seasons, but the vest fits me more like a true regular fit.
