My daughter purchased this online and wore it only once for a short time. It's a 3-piece set: a short-sleeved T-shirt, a vest, and a skirt. The skirt has an elastic waistband, making it easy to wear. The size is S. It's a high-quality, very cute costume, but she won't be wearing it again, so I'm selling it. Would it be suitable for this year's Disney Halloween? Please understand that this is a pre-owned item that has been stored at home. Thank you.
