Size small
I'm 5'4" shorter torso, 32 DD, 120-125 lbs, longer arms, slim and lanky. The size small fit me well, the collar is removable and adds that extra level up you want to dress up or down. The sleeves are perfect on me, you can easily tailor the sleeves if they are a bit long. The chest is nice a bit roomy for me as I do not wear molded cups but again an easy fix if it were pertinent, I however don't have an issue with it being a bit less fitted in the chest because I plan to layer in the cold. I also find that the belt and waist fit so nice that it's unnecessary with the deep v notched collar. The bottom half of the coat drapes beautifully and gives a flattering figure! I tested it with longer skirts and dresses and it looks so beautiful and feminine. The coat is lined but not insulated, it has a nice weight to it, I feel a sweater would be enough to keep warm in most conditions and the goatskin is superb. It is a deep burnt brown color very dark and rich, the fur collar adds a beautiful contrast and warmth to it without being too warm toned that a cool toned individual like myself couldn't wear it close to her skin. This jacket is a dream!!! I would mention the waist button fit me perfectly but if you are bigger in the waist maybe go up one size unless you don't mind moving the button or just tying it alone. All in all this coat made me feel like a princess!
