These are tights from WOLF & RITA. The size is unknown, but the actual measurement from heel to toe is about 10cm. Please check the third photo. I think I wore these when my child was about 1 to 2.5 years old. I've only worn them a few times. I also sell socks and leggings from the same brand, so please take a look at my shop if you'd like ^ ^ - Brand: WOLF & RITA - Color: Green - Design: Zigzag pattern - Material: Cotton blend - Size: Details unknown
