The Sebastian Long Sleeve Polo Shirt - Burnt Sienna
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 warm and textured Burnt Sienna tones.
Taken alone, the Sebastian is a charming statement piece for a cool coastal drive. Layered with DDM’s suave linen blazer, the sketch becomes slightly more refined.
Once again Dandy’s eye for the timeless achieves perfect focus, resulting in an expertly crafted polo LS to add to the essential knitwear collection.
Designed with love in California.

Perfect fit.
I love the this shirt! Very unique design that you don’t see everywhere, just like all the other shirts and pants I’ve purchased from Dandy. The fit is always on point. Also I love also their music on Spotify!! I’m loving the whole vibe of Dandy.
My favorite dandy shirt
This is probably my favorite of every item I have received from Dandy Del Mar. I do wish the collar was a bit bigger or it came in other colors, but otherwise I love it.
Wish they were longer on torso.
These shirts are awesome material and look great. It seems though even when you size up the length on the torso does not seem to increase. I ordered a XXL and I am 6ft 3, 190 lbs and if I raise my arms my entire belly gets exposed. Seems to happen with other shirts too, including tank tops and the Cannes waffle knit shirt. Wish they had longer versions. The Cannes waffle shorts are great fit and look great though.
