In all honesty though - I doubt being in their 70's and 80's these two would want to wear anything low cut. Spaniel's ears spring to mind!
I'm sure they'd act much the same if they were young and pretty again!

I applaud her for her marathon achievement, but her singing voice and over exposure on TV and media events is pretty irritating to me
