The only information that I have is the information on the stickers which states "Under Bust Corset; Size; Black Leather 5 Hooks" or "Over-Bust Corset; Size; Black Satin 6 Hooks". There are also very small labels on the inside with just the size on them.
The Corset Black Satin Overbust or Faux Leather Underbust, designed for Sexy Lingerie, would be an ideal fit for those seeking a blend of glamour and support in their attire.
