This is a new adhesive backless lift-up bra. The size is C, but it's not something to worry about too much. Unlike a NuBra, this doesn't add volume itself; it lifts your own breasts to create cleavage. It has a front hook, so you can adjust the cleavage as you like. Since there's nothing on the back, it's perfect for dresses, swimsuits, etc. It's also water-resistant, so you can use it with swimwear. You can wash it after use and reuse it many times. I'm also selling various other items! #mayuchin #NuBra #BraPads #Backless #OpenBack #Dress #OnePiece #PushUpBra #BeautifulBreasts #Swimsuit #Pool #Beach #Sea #Bikini
