A beautiful unique combination of hoodie, henley and a two tone look. Pictured above is under my jean jacket. I'm 5" x 6", 140lbs and the small size fits me perfectly - a little "a little" for a tight size but I love it. (and it stretches) You should be really skinny and small for a size small and the material is thin and comfortable with little stretch. My wife says I look cute and sexy in it which means she is happy.
