Size up
I love the ruching on this hoodie, which is why i ordered it. i'm typically a size small, 34b, 130lbs but the hoodie was a bit tight in the waist and around the bottom band. i might order it in a medium (although the sleeves will likely be too long) the only thing that makes me hesitate is the color. it's more of a brown gray (instead of just gray as you see on your computer screen.).
