The size is listed as 160 because that's the highest option available, but the actual size is 170. It's a size that adults might be able to wear. Unused, no tags, but there are wrinkles from storage. Length: 45cm Waist: 30cm (elastic) I have too many clothes and can't wear this, so I'm selling it. For those who like #TartineEtChocolat #SenseOfWonder #ToccaBambini #Kumikyoku #KateSpade #MezzoPiano #KPknitplanner #HakkaKids #familiar etc.
