I always thought the heavy duty PUL with velcro looked quite a bit like Bumgenius. Also the ultra soft look like FuzziBunz Perfect Size(but the Kawaii are onesize wirh a snap down rise, the PS are sized obviously) also the round tabs with snap Kawaii look a bit like Thirsties. Just my thoughts though. I'm sure others don't see it.
