The ribbed t shirt lives or dies on fabric weight and how the ribs actually sit on the body. Get it wrong and it looks like something rescued from a three pack. Get it right and it becomes one of those pieces you reach for constantly because it works under an overshirt, on its own in warmer months, and tucked into tailored trousers without looking like you’re trying too hard. We’ve spent time finding the ones where the cotton has enough substance to hold its shape through a full day, where the rib pattern is close enough to read as considered rather than basic, and where the fit through the chest and shoulders doesn’t require a compromise. Crew neck or a slightly wider collar both have their place here. What they share is that none of them look cheap in person, which is the only bar that actually matters. These are the ones worth adding to the rotation.
