So i been looking into this for my submissive, but we had concerns about how noticeable they are in a public environment for example work when worn under clothes. Most of them seem quite large and clumpy - has any one got recommendations on slightly more subtle belts that can be worn out in public without showing through clothes?
You might check out the Bondage Gear section and do a search. However, she may have to change her wardrobe (e.g. only wear loose-fitting skirts/dresses) to compensate.
