It's bit weird looking cuz the transparency of the clothing textures affects the skin. I dunno why but it's maybe due to compatibility issue with Blender 4.3 and the VRM add-on. But it's fine for rendering in Blender.
Blender4.3とVRMアドオンとの相性なのか、服のテクスチャの透明部分が肌にまで影響して変な表示になってますが、Blenderでレンダリングする分には大丈夫です。
