Quality t-shirt brands that offer minimal shrinkage include Buck Mason, Mack Weldon, Banana Republic, and LL Bean. They use pre-shrunk cotton, modal, and silk blend fabrics. As long as you wash in cold water and tumble dry low, their shirts maintain their fit and size excellently. For some specific recommendations, Mack Weldon's 18.5 momme silk blend tee resists shrinking. Buck Mason's slub cotton holds its slim shape after washing. Banana Republic's Supima cotton doesn't shrink up. And LL Bean's classic cotton tee keeps its relaxed fit. For shirts that stay the same size, look for these brands using high-quality preshrunk and blended fabrics.
