Before you even think about layering, check the fit. A graphic tee that's too tight looks like it's borrowed from a kid's size. Too baggy, and you're swimming in fabric. The sweet spot? The shoulder seam should sit right at your shoulder edge. The sleeves should end around mid-bicep. The hem should hit around your waist or just below—not past your hips.

If your Windbar tee is slightly oversized, that's fine. You can still make it work. Just balance it out with a more fitted layer on top, like a denim jacket or a bomber. If it's on the slim side, wear it alone or under an open overshirt.
