Kazuha cosplay best

Product Name: Kazuha cosplay best
Kazuha from Genshin Impact best cosplay from Miccostumes. It's labeled as an XL but I feel like it would fit a US Medium best. I bought it from another seller on mercari and while it was a great transaction and the item came exactly as described, it just didn't fit me. I used the photos they took and added in the alterations they had made. All in all, it's a nice costume and it's a shame it was too small for me.
