Mid-weight wool blend construction. Warm enough for fall and spring, structured enough to wear as a standalone layer.

Clean regular fit with faux-horn buttons and front patch pocket. Tailored detail without formality.

57% polyester, 14% wool, 15% viscose, 14% cotton blend. Soft handfeel with enough body to hold its shape through a full day.

Versatile across three seasons. Works over a tee, under a heavier coat, or on its own when the temperature sits in between.

The gap between a shirt and a jacket is where most wardrobes fall short. The Otto fills it exactly.

The Otto Wool Overshirt sits at the intersection of tailoring and ease. The mid-weight blend carries enough structure to read as intentional without the stiffness of a formal layer. Faux-horn buttons and a front patch pocket add refined detail without competing for attention. The regular fit moves through a full day without pulling and stays composed without effort.

Diamond built the Otto as a three-season answer to the question of what goes between a shirt and a coat. Fall through spring, indoor to outdoor, dressed or relaxed. Layer it over a lightweight knit on colder days. Wear it alone on the days that sit just above comfortable. It reads correctly in either direction.

The Otto. Three seasons, one layer.
