These ribbed sweaters fit to the body.  There is a lot of give to them so just like reviewers have stated buy a size down.  I take an XL but ordered Large and it fit perfectly.  I did notice that the label stated to hand wash these and lay flat to dry.  I'm certain these will shrink if put in a dryer.  These sweaters are classic ribbed turtle necks that look great under my blazers or trench.  Very distinguished you will look especially if you have a physique!  enjoy and buy all the colors!
