This handy little thong really helped smooth things out under the Claire Underwood dress. It's a comfortable thong with smoothing/holding-in to just the right degree. (PS I did size up to make sure no death grip was involved.)

And -- crazy -- but there is a Spanx store in the Washington-Reagan airport! Yes, that is where I bought it.

Anyway, check it out. Well worth a try: http://www.spanx.com/panties/t.....1689=46039
