Masakori Masakari-sama, I have confirmed your profile. I look forward to your purchase. This is Triumph bridal innerwear, size C70. I purchased it new and used it once for my wedding in September 2025. It has been home-cleaned. I've inspected it myself, and it appears to be free of stains. The shoulder straps, etc., are all attached and removable. See photo 7. I wore a dress with an open back, but the innerwear was not visible.
