I absolutely love this sweater, I bought like 6, lol. I am 5'4" and 123 lbs., I ordered 2 small and 4 medium. The small fit but perfectly, so I ordered the 4 medium for just a little bit of a bigger fit, perfect! I absolutely LOVE this sweater, my only maybe small complaint was I wish the sleeves were a bit longer, they're a perfect fit but I prefer my sleeves to go over the backs of my hands and these reach the wrist just barely. I would not wash and dry this sweater, definitely delicate wash aSee full review
