Purchased at AEON around November 2023. The size is 50-70, but I bought it before the baby was born, so I wasn't sure about the newborn size... When I tried it on, it was a bit too big as a vest, so it was too big to wear during the winter at 50cm. By the time the baby was one year old the following winter, it was already too small. It seems like it would be just right for a baby born in spring or summer. (This is just my personal opinion) I'm selling it because it's a waste since it was only worn a few times. Would anyone who doesn't mind a used item be interested? Please note that the Snoopy's face is a bit fuzzy from washing, so I will trim it with scissors before shipping (see photo). A cute fleece vest with Snoopy embroidery. - Design: Snoopy embroidery and star pattern - Material: Fleece - Color: Cream - Buttons: Wooden buttons - Size: ~95cm Thank you for looking.
