Demon Slayer Kanao New Cosplay retailer Costume Small

Product Name: Demon Slayer Kanao New Cosplay retailer Costume Small
Bought this and it's too small for me. Though the tag says it's a medium it runs small. Comes with everything shown in pictures. Brand is Miccostumes. It is completely unused and it hasn't even been tried on. Just taken out of the packaging. The best fit would be for someone between the heights of 4'9 and 5'3 and below 125 pounds. Honestly this would be a great kids costume because honestly this is NOT REALLY made retailer for adults. If you have any questions or offers pls DM me! I usually ship within 24-48 hours of ordering. I will not allow for returns/refunds if the sizing is incorrect for you!.
