This is a LUNA Natural Up Night Bra & Shorts Set. It is new and unused. The retail price is ¥7980. The size is M (bust 79-87cm) (hips 87-95cm) The color is the popular Airy Peach. I purchased the wrong size, so I am selling it. Product Description (from the official website): This night bra is made for AAA cup to C cup sizes. It has obtained patents for the "non-slip sheet" and "hammock structure," and has achieved Japan's first special design to shape the "ω (omega) line." By shaping the ω (omega) line, the bust is gathered in the center while sleeping, creating and maintaining a three-dimensional bust. There is a wide variety of colors, so you can enjoy a color that matches your mood. #nightbra
