No matter the neighborhood, it’s a rare day in San Francisco that you can walk around with just a T-shirt, like the ones above from Stewart and Brown, Organik, and Loomstate. Nevertheless, keeping a few tees handy year round is a good idea. That’s because they’re perfect for layering underneath a sweater or a jacket. As for the ones above, they’re made of 100% organic cotton. With electric colors like these, who needs sunshine? In the interest of full disclosure, I own the Stewart and Brown, and Organik T-shirts. 😉
