Putting together a fancy dress rail for my niece (Disney princess dresses and superheroes!) I'm ordering some bits off Vinted but stuck to know what size to pick! She's 3 but really tall and wears size 4-5. The sizes seem to be 3-4, 5-6 and 7-8. I'm thinking 5-6 but a friend has said that kids costumes run really small! But 7-8 will be far too big right?
Pointless post but I am stressed 🤣 my sister has no idea as niece has only just started to get into dressing up!! I want it to be a surprise for her birthday so can't get her to try one on really!
