I absolutely love this sweater. I am 5’6, weigh 143 and am a 38D. I ordered a medium and it fits great! It’s not tight, but is form fitting, so I probably could have ordered a large for just a little more room. The sleeves are on the longer side. I can either cuff them, or leave them uncuffed. It is a heavier weight, and very soft. I would definitely recommend.
