Like wearing a cozy cloud
This sweater is fairly substantial overall, yet has this delightful loftiness to it that makes it feel like a cozy cloud comforting you. I'm 5'11" ~200lbs and a medium is perfect. Medium in the crew neck styled sweaters for my build seem to be the way to go (and this extends to previous years as well). It's a beautiful design, sleeves are on the longer side, but only just barely.
