Black Cat Halloween Costume Size not indicated. Flat measurements: Shoulder width: 45 cm Length: 53 cm My child wore this when they were 4 years old. I think it can be worn by children aged 3 to 5. I paired it with a long-sleeved T-shirt and leggings, wearing it like a poncho. It's very cute! ☺︎ It's also cute paired with a frilly skirt. The hat has an elastic band, so it's secure. There is a feeling of wear. Please understand before purchasing. Thank you for looking.
