Luma has the same problem! Maybe try the silk step in harnesses? I've seen threads..let me find it.

Same concept as the bb I think, but silk vs. Leather? Cant beat that. Also i know some of the bb's are softer than other colors. There is also a harness liner available on the bb website. Let me know which route you go...Luma has super sensitive skin lately and the bb tears her UP.
