Oshi no Ko Arima Kana Cosplay Costume with Wig Purchased on Amazon for 6,500 yen. I believe the size was M. I was unable to confirm the purchase history on Amazon, so please be aware that the size may be different from what is stated. I bought this for Halloween, but I ended up buying something else, so it has been unused. Thank you for looking. Oshi no Ko Ai Hoshino Aqua Ruby
