I also have no butt and extra belly fat, so I ordered 2 undergarments to compare: 1 with only foam pads and 2) with the silicone pads. Both gave me superb belly control. Also, even though they were heavier (as advertised), I preferred the silicone butt pads which did give me the boost and shape I needed, so I kept those. Received the order quicker than expected! Highly recommend Lovemybubbles!
