I bought a multi-pack of black socks (school socks actually!) from M&S, they are supposed to be size 4-7 but have shrunk so badly that they feel like they’re cutting the circulation off at my ankles when I put them on. My feet are about size 5.5.
I want to go out and buy some nice comfy socks but don’t want the same thing to happen again when I wash them. Any recommendations?
