Amazing
I don't know if I mentioned it, but I found that backpack strapping (black, polyurethane) that we all love for rigging our suits, makes wonderful boning for the garment. I just popped brass fasteners through my piece into the stapping, leaving enough for the other pieces around it. You can get nice and snug, and it can still flex. Bonus is that the straps are black, and any gaps will be invisible by default! Now, its not as strong as legitimate rivets in leather buy hey, I'm in university haha gotta save that cash.
