What bra should we wear with backless dresses

We all love to wear backless dresses, but we often think, it's not possible to use them elegantly without a bra. 

I don't like to see any straps, even the transparent ones in silicone, so when I want to wear one of these dresses, I wear a self-adhesive silicone strapless bra. 

There are many types, and they are easy to find in the best lingerie shops. It's a bra that we all should have in our wardrobes.
