“Sizing for between-sizes?
As usual, with SML etc. sizing, for between-sizes, it can be a guess. Say, for ML, would you order up?/down? If order up, would this be comfy with more than 1 layers underneath? (Seeking something for outer-layer is mild-weather, but - refurbish, because it's Smartwool - has more usefulness than just that.)
The sweater has a generous cut, and loose knit. I'm a 36-C, around 150pounds, and find the Med to be roomy enough to layer underneath, which is a good thing since it's so scratchy. Probably not anything bulky though because the sweater itself is quite chunky. Again because of the looser knit, it's not wind proof. You can dress is up or down easily. Hope this helps.
