>>10943405It's a crap reverse bunny suit because it's still covering/isn't covering some of the same areas a normal bunny suit would, OP pic is basically just a bunny suit minus the top part and not an actual reverse bunny suit.
If you're just asking "why isn't there reverse bunny suit cosplay" in general, and not this specific one, I have seen those cosplays, they exist. But since the middle is nearly nude, it's going to be locked behind paid tier walls of OF girls or strictly at after dark 21+ ecchi cons
