Obviously I'm right between the sizes. I ordered medium first and it was huge! Shoulders hung from my arms. The handcuffs reached almost to my fingertips. I'm not very skinny, but we're a match. So I swapped for a small one. I'll keep the small one but it's a whole different size. Only the sleeves are a bit short. The shoulders are almost too tense. And when I pull it up, it's very comfortable. For reference, I'm 5'8" and weigh 170 pounds. I usually wear a medium sized t-shirt.
