These little cotton pointelle socks are one size fits all as they are super stretchy without a defined heal. They will fit higher up on younger babies and lower down on older girls.
Recommended to fit 3/6mths upto 3years.
Baby in photo is 4 months old and girl in photo 1.5 years for reference of length when wearing.
After washing just straighten out the cotton lace while wet and leave to air dry.
