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 ordered this top in a size medium. It is a very comfortable, relaxed fit on me. If you want it more fitted, I would suggest going down one size. I do own over 10 Ani tops, in multiple colors. However, this sage color...WOW! This top can be dressed up or down. It feels so luxurious on. Its light weight, but keeps you warm if it gets a little cooler. When wearing this top, its an effortless look. Yet, you're still well put together. I like that it can be worn various ways as well. Tied, opened, casual, dressy, for the beach, at home etc.
