A school day essential, M&S' long sleeve school shirt comes in a helpful three pack with timesaving Easy to Iron technology and, for the younger sizes (up to 8 years), M&S' practical Expandicuff™ technology. These shirts are a regular fit, so they look great and sit well on the body with plenty of room to breathe. M&S' school shirts are made from a crisp cotton mix that’s both smart and comfortable, perfect to wear with a school tie and tucked into black or grey trousers. We are transitioning the polyester in this garment to recycled polyester. While we transition, customers may receive items made with either sustainable sourced cotton and recycled polyester or just sustainable sourced cotton and polyester. Regular Fit – M&S' classic regular fit.
