Query: The Best Invention since a Blow-Dryer!

These are the coolest things ever made. I have been searching for a product like this forever and I could only find what used to be called "lingerie helpers" from the 50's or 60's (I think) which didn't quite do the job. No more buying those "speciality" bras that cost a bundle or those racerbacks that didn't quite fit right. I just put these on my favorite bra and don't even know it is there. Now there is no excuse for me to ever see anyones bright pink bra straps peeking out from their shirts. I am just jealous that the woman who invented it is going to make millions and I am not!!!
