HOSHINA Mizuki wears Hakama. A white short sleeves and scarlet skirt, this is a traditional style of Miko. Miko is a woman who serve God in Shinto. Of course, she's not a real Miko. This is the only cosplay, and this costume is pretty suits her.
袴姿の星名美津紀さん。白い小袖と緋色の袴は巫女の伝統的な衣装様式です。巫女とは日本の神に仕える女性の呼称です。もちろん彼女は本当の巫女ではなく単なるコスプレなんですが、よく似合ってますね。
