Politicians and their guests arrived at the Senate hall on Monday morning dressed in simple but fashionable garbs for the opening session of the 17th Congress, a few hours ahead of President Rodrigo Duterte's third State of the Nation address.

Senator Nancy Binay, whose SONA look has always been one of the most-awaited, was clad in a baby blue Filipiniana gown made by Randy Ortiz.

The fashion-forward wife of Senator Chiz Escudero, Heart Evangelista meanwhile wore a classic Mark Bumgarner white Filipiniana and matched it with a nude peep toe heels. 

Jinkee Pacquiao who is always up-to-the-minute when it comes to fashion, looked modish dressed in a Filipiniana pantsuit. She wore her hair neatly tied in a low ponytail.

Senator Grace Poe decided to keep it simple in a white terno with a few beaded details. Check out a few of our favorite looks in this gallery.
