Ok,so I broke down and bought the Strap Perfect contraption.I had just got burned on the stupid Bumpits! They do not work for me-----sending them back,but I will eat the shipping,which was expensive.I did not order Strap Perfect online.I had saw it at WalGreen's and saw it at the Dollar Store and thought why not.It was only $10 for 2 sets of 3 and 24 pieces of invisible apparel tape.OMG! I love it.Wore it all day yesterday and slept in it and wore it again today.
It does give you lift but does not squeeze too tightly.It keeps your cleavage pushed together without pushing them waaaay up.It does really work well with the tank top-----no straps showing.I used to tell people if they could see my bra straps then at least they knew I had one on,but it really does look better without those straps.Just thought I would share.

HAHA!!! I also bought the bumpits and they didn't work for me either! I couldnt hide them in my hair, it looked really silly!
I have been tempted to buy the strap perfect, but I can't be bothered to order them, I havent found any in any stores. But, now that you say they work well... hmmm... They seem like such a simple concept, maybe I will try and make some? haha or get my boyfriend too, he's pretty handy.
