Man of the House (2005, with Tommy Lee Jones) 8)
The cheerleaders in that film are women after our own hearts. They look after their bodies and this; my favorite line form the movie.
"All right. We'll cave on the first two. But we absolutely must maintain navel visibility."
As for movies, I'd like to recommend "Texas Chainsaw 3D". It has some disturbing and gory moments but apart form that the two leading ladies, especially Alexandra Daddario, show plenty of midriff!
