Leave it to Miley Cyrus to pick a lovely black Tom Ford dress for a charity gala.

This is what she wore to the Wednesday night’s amfAR Inspiration Gala in Hollywood.

And her mom Tish seemed to love it. She posed by her side throughout the night.

And then came Rihanna in a different Tom Ford creation. Did she out-sexy Miley?

Most chatter this morning gives the prize for most-daring, barely-there, boob-baring outfit to Ms. Cyrus.
