Set for Keqing from Genshin Impact. Character wig from Sānfēn Mèngxiǎng (三分妄想) is used. Worn once indoors, and used at a sports festival, so it has moved around a bit and has some slight styling imperfections. It will be compressed for shipping, so the ahoge (cowlick) will be somewhat flattened. Applying heat to the base should allow you to reshape it to the condition shown in the image.
