After lamenting over breast form shift, I had an epiphany. I ran to the bedroom, grabbed my bra and my 22lbs worth of breasts, and strapped them all on, as usual. Then, I took THREE Genie bras and put them on over my Goddess bra. I then tied the straps together, in the back behind my neck, using a shoelace. The result: NO SLIPPAGE! My boobs are completely secure! I takes a couple good jumps to get them to slip. I can even bend over without having them flop around or separate from my chest! Needless to say, I am completely overjoyed!
