So I bought a pack of these in 2018. Now I'm 24 and wanted to buy something black for work but I wear a 12-24 month size all the time? Confusion. I was the fifth women's shoe size and now the sixth. I've always thought that their small size is fine after washing and that they should stretch to fit the foot. Just a little weird although I love these socks and have loved them for 4 years!
