Harbor Stripe

Harbor Stripe is inspired by harbor sails, dockside umbrellas, striped canvas, and the crisp air of a summer morning by the water.

Deep navy and white vertical stripes bring a classic nautical rhythm, like watching boats prepare to leave the harbor. Tiny coastal marks hidden between the lines make it feel clean, playful, and full of anticipation.

The print keeps that coastal feeling light and understated — not loud, but full of wind, direction, and the quiet excitement of moving closer to the coast.
