I’m 5’7” and 140#. Bought a black color in the medium size. I don’t like oversized or snug sweaters and this fit just right. The sleeves are slightly bell shaped which gives the sweater some personality. Weave is not tight but also not see-thru. The ribbing on the neck, bottom and cuffs has a tighter weave and a hem roll. Those areas are lightly fitted but not snug. Sleeve length was a nice surprise as they extend over my wrists - a rarity for my height. A very nice, flattering look that can be dressed up or worn casually.
