The Sebastian Knit Polo Shirt - Shell
Nothing speaks of refinement quite like Dandy Del Mar’s Sebastian Knit, where the polo meets the summer sweater on a sunlit swell along the Mediterranean. This one’s for the dreamers who live outside of time . . . the romantics and bon vivants.
This expertly tailored Italian knit features cuffs at the waist and sleeves, a finely ribbed collar, and a charming buttonless front placket for the right chest exposure. See you on the water Dandy.

Uncommon appeal and uncommon quality
I found Dandy Delmar through one of those serpentine web experiences that begins for one reason and delivers something unexpected. Once on the website, I saw the Sebastian shirt, liked it immediately yet was curious about sizing. I emailed support and was answered within 3-4 hours, great first impression. With some sizing info in-hand I ordered two shirts, both 3X. Fyi, for 5'10" 220lb guys, 48" Chest, the 3x fits perfectly. The shirts shipped quickly and fit perfectly. The quality is evident from the moment you feel the fabric. I look forward to adding to my purchases.
Nice!
I just received my shirt and I absolutely love it. I'm 5'8, 165 lbs, muscular/lean and it fits perfectly. An extra inch on the length might have been a better fit but overall it fits well. The sleeves hang perfectly and show off my arms nicely. I will be ordering more shirts. New loyal customer.
Great shirt
Love the shirt - I’ve gotten compliments both times I’ve worn it. The shirt does need to be washed delicately. I’m considering buying another color. Thanks Dandy!
