Handsomely trimmed from the softest sweater-knit cotton, the Sebastian Long Sleeve rounds out the seasonal solar shift with a robust long-sleeve design, featuring softly textured neutral tones. Taken alone, the Sebastian Long Sleeve Polo is a charming statement piece for a cool coastal drive.

Layered with DDM’s linen blazer, the sketch becomes slightly more refined. Once again Dandy’s eye for the timeless achieves perfect focus, resulting in an expertly crafted long sleeve polo to add to the essential knitwear collection.

Designed with love in California.
