Robe of Yūen is one of Erza Scarlet's armors.
This armor is a beautiful Japanese/Chinese attire reminiscent of a revealing kimono. It consists of a short sleeveless tunic decorated with many flower motifs, which has revealing openings on the sides and front, exposing much of Erza’s chest, while both of her forearms are covered in white bandages. These openings are held closed by a large, dark obi, which has a thin red rope tied around it, sporting a wide closing ribbon on the back. What also closes the openings of this armor is a lighter and smaller white belt, which is wrapped around a pink, flower-patterned cloth circling Erza’s waist on the back and the sides. On the front, her groin is covered by a long cloth hanging down from her tunic, while the back is circled by another one, almost reaching down to her knees, possessing jagged edges. Another cloth is also hanging down from the sides, held closed by the ribbon on her back. This cloth has a yellow border and is folded to the outside and split into multiple edges at the middle of the cloth, pointing away from Erza's body. Erza’s legs are covered by light stockings reaching up to her thighs, and her feet have simple sandals.
- Bisentō: The outfit comes equipped with a bisentō, a large Japanese polearm similar to a halberd. The blade has a cove at the start of the blunt side of the blade, a small hole above the cove, and an even smaller hole above the small hole.
