Basics Slim Fit Seaport Navy Cotton Crepe Halfsleeves Shirts

Seaport Navy slim fit shirt in 100% cotton crepe—a no-fuss half-sleeve piece built for heat and regular rotation. The cotton crepe weave sits at around 140 GSM, giving it enough weight to hold shape through the day without feeling stiff or heavy; the slight texture also masks minor creasing better than plain weaves, which matters if you're moving between meetings and aren't pressing between wears.

This works as your default shirt for humid months when you need something that breathes but still reads as put-together. The navy shade pairs easily with grey, charcoal, or black trousers—or layer it under our other cotton shirts if the office runs cold. If you prefer a looser cut, our plain designs also come in relaxed fits.

The slim fit runs close through the chest and shoulders; if you're between sizes, size up. Wash in cool water and air-dry to preserve the crepe texture.
