Size 4 in this brand fits like an 8-10 or large! (For reference I usually fit into size 4 and tend to get a medium if I’m over sizing a sweater; this is a bit bigger of a fit on me than I usually like.) Great classic sweater by posh British cashmere brand! Lightly worn so no pilling, but there was a tiny 1/8” hole in the back, at the bottom left, that I invisibly fixed from within the weave, Japanese style! I included before and after pics so you can see, but the only way to really view it is by holding the sweater up to the light.
