Olive Colored Wool-Blend Sweater with Button detail

This is a cute and flattering size x-small sweater from Ann Taylor Loft. It is 3/4 length sleeve, and has a button detail on the back. The color is olive green to me, but my parter says it’s brown? It’s definitely earthy and perfect for fall! It is worn and in good shape, there is some pilling on the sweater that you can see in photos.
