One would think they'd design shirts/blouses with the cups and extra support built right in so as to remove the psi from the shoulder straps. You could design the thing so it would accept different cup sizes.
OK, I'm having difficulty visualizing exactly how this would work. Seems like that would hold your bra "down."
I got that in a birthday card. My group had an over the hill party. Took me a minute too. Think low hanging fruit to your knees....
That reminds me of when a patron would come into the library and ask me about a book. They would say, "I can't remember the title." Me... "Who was the author." Patron... "I can't remember but it was about a man who had a dog and the dog went missing," The books were cataloged by author, title, and subject so I could find them most of the time. They thought I was some kind of genius. I never told them my secret.
