Jcrew Men’s Slim Untucked Long Sleeve Button up Main color is blue with floral in white, orange, and yellow 100% cotton. Button-down collar. Machine wash. Like new Comes from a pet and smoke free home We've revamped the super-versatile Secret Wash shirt with premium 100 percent cotton 100s two-ply yarns, plus an improved fit. "100s" refers to a finer yarn size, and "two-ply" means two yarns are twisted together to make a single thread. The result is smoother, stronger fabric. We also use our (proprietary) multistep wash process to achieve a soft, broken-in feel from day one. It's effortlessly casual right out of the dryer and easily polished with a quick iron. Long story short: The customer favorite since 2005 is now better than ever.
