Most blouses are made of opaque material or show just the ghost or a bra through the fabric (which many of us like).
What's proper to show? I've got a white silk shirt on right now, and a dark printed bra that shows through without revealing a lot of detail. Ought I be wearing a slip or camisole as well, were I to walk out the door? The bra could still be seen through the lace of the camisole and you'd see multiple straps, but is that the issue?
