This is the Marc Ecko Hero Shirt. It is a Button Down Shirt that comes from Marc Ecko’s contemporary collection called “Cut and Sew”. I really like how they did something as simple as using contrasting colour on the topstitching to give the shirt its design.
The shirt comes in three different colours [black, grey, and baby blue] and can be found on the Ecko online store. If you are okay with searching through clothing racks then The Bay also carries the Marc Ecko clothing.
