Although it is new and unused, please understand that it has been in someone's possession. My child outgrew them without wearing them. The size listed on Mercari doesn't have a perfect match, so I've listed it as 11-11.5, but the size is 10-12. (I forgot the exact size, but when laid flat and measured with a ruler, it was 10.5, so I believe the 10-12 size is correct!) Baby high socks, baby loose socks, apres les cours, ivory.
