For a layered look in Calvin Klein men’s knitwear, sizing up is usually the safer move—especially if you plan to wear a button-down, tee, or lightweight hoodie underneath. A slightly roomier fit helps the sweater sit cleanly over base layers without pulling at the shoulders, riding up at the hem, or feeling tight through the chest and upper arms.
That said, don’t automatically go up a full size. If you’re layering something thin (like a fitted tee) under a merino or fine-gauge sweater, your regular size often still works and looks sharper. Fine knits are designed to drape closer to the body; too much extra room can make the torso look boxy or cause the neckline to sag.
Consider sizing down only when the knitwear already runs relaxed or oversized, or when you want a cleaner, tailored top layer over a very minimal base. If the shoulders drop past your natural shoulder point or the sleeves bunch heavily at the cuffs in your usual size, going down can restore structure—just make sure you can still move comfortably and the sweater doesn’t cling across the back when you reach forward.
A quick fit check for layering: in the right size, you should be able to pinch a small amount of fabric at the sides without the sweater ballooning, and you should be able to raise your arms without the hem lifting excessively. If you’re between sizes, choose the larger size for chunky knits and the smaller size for fine-gauge styles—unless you’re stacking multiple layers, in which case the larger option typically wins.

The shoulder seam should land close to your natural shoulder edge, and the chest should feel comfortable without stretching or pulling. You want enough room to move and breathe, but not so much that the fabric collapses or looks sloppy.
