I'm always nervous getting turtlenecks because I don't like it when the collars are too tight. This one is perfect. For reference, I'm 5' 7\\\\\\\" around 115 ish lbs, and I got a medium (I always size up with sweaters). The fit on me looks just like the photo. It is seriously so freaking soft. I can't wait until it's cold enough to wear this. Love the fit, love the fabric, love everything.
