The greenbriar is a nice colour. It is true to size. I am slim, 5 7', 110 pounds and got the XS. It has a bit of stretch which is nice if you want to fit a thicker top underneath. I like the button up collar. It is warm and not itchy at all. The only problem I have is that if you have a button up, high collar like this and short bottom length, it doesn't balance out the figure properly. It should be at least below your rear. Other than that it's a great sweater.
I love this sweater! It is warm and soft and attractive. I ordered a large and then exchanged for medium and it's just perfecdt--that makes me think it runs a little large. I'm 5'3 and 155 and it's just perfect. I would definitely recommend this item--have 2 of them!
