Kamakura OCBDs: 4 Styles Compared

Light blue collared shirt with buttons and a folded collar.

The OCBD — Oxford Cloth Button-Down shirt — may seem like a classic staple, but don’t be fooled by its simplicity. At Kamakura Shirts, we offer a range of OCBDs tailored to suit different occasions and styles.

Beyond just silhouette variations, we pay meticulous attention to every detail, from collar length and interlining to button spacing. Since the OCBD is often worn without a tie, we’ve taken particular care in perfecting the collar’s appearance — its “face” — to ensure it looks beautiful on its own. On this page, we’ll introduce the unique features and appeal of each OCBD. Find the one that brings out the best in your personal style.
