I was gonna get a small, but it was sold out, then the medium sold out, so I took my chances and bought the size large. This is immediately turned into my favorite cardigan the moment I put it on. The size large is actually perfect bc this is slightly cropped. I’m 5’3 and 140lbs and usually small or medium is my go to size. But this size fits perfectly if you want to cover you abdomen. Also it is incredibly soft and bc of the design of the buttons and can also be worn off shoulder!
