I never thought that I would be so in love with the strapless styles in my 50's! It's a great look and neck line when you layer it so don't be afraid, just try it! I still keep my normal bra on (the girl's aren't where they used to be!) with a plain strap showing.
I pair this dress with a little blazer and a pair of strappy sandals and I'm off and running--with style!
