With a BBL - if you are constantly fluctuating weight/ dress size, then the BBL acts accordingly. For example if you lose or gain weight your BBL will become larger or smaller. Kim Kardashian has recently and openly lost a large amount of weight, however her BBL is still a PERFECT HOURGLASS no matter what size she is. Does she have hip/buttock implants? Her figure never fluctuates. How does she permanently maintain it? This is why im not fully convinced she has a BBL?
