Benetton underwear. I bought these thinking they'd be for a night bra, but they're the wrong size, so I'm selling them at a discount. These are originally 4900 yen each. I'm also selling the matching shorts, so please inquire if you'd like to purchase them as a set. There are no wires. The size is M in Japanese sizing, and it's specified for a B cup. The material is stretchy and similar to a night bra (with pads included).
