Size: The marking is faded, but it's about 18-20cm. I've measured it, so please compare it with your child's socks. Brand: Ralph Lauren Condition: No noticeable flaws. Not used for everyday wear. Worn about 5 times for special occasions. There is some soiling and wear and tear due to the white color. Please refrain from purchasing if you are sensitive or cannot accept even minor oversights, as these have been worn by a child. Thank you for your understanding of used items. ◇ Classic / White / Simple ◇ Pony mark ◇ Formal Boys Girls Children's Clothing POLO
