I am 5' 1". I weigh 155 pounds. My bust is 42" (36 DD). My waist is 37". I am in between a size medium and a size large. I purchased this cardigan in a size medium. It fit great! I am so glad I didn't go with the size large. It (in my opinion) would've been too big on me, for my liking, for this look. Sometimes its hard for me to decide what size to get , in cardigans like this, because I'm in between sizes. That's why I always read the reviews. However, many times the reviews don't help because there's no information about other ladies measurements. I hope this information helps you decide on what size you should get. It looks so good with the matching skirt. I love anything hounds tooth. The quality is awesome. It is a little thick, but not heavy, nor is it a scratchy material. The comfort and stretch, always welcomed. Such a classic look.
