M&S' short sleeve school shirt is a school day staple, available here in a handy extra value three pack. Each shirt is designed with timesaving Easy to Iron technology, a quick press and they are ready to go. These shirts are slim fitting with a narrower cut that fits closer to the body. We are transitioning the polyester in this garment to recycled polyester. While we transition, customers may receive items made with either responsibly sourced cotton and recycled polyester or just responsibly sourced cotton and polyester.
