Who: Gisele Bündchen.

When: Friday, August 5.

Where: The 2016 Summer Olympics opening ceremony in Rio De Janeiro, Brazil.

What: A sparkling gold gown by Alexandre Herchcovitch.

Why: Bündchen commands the Rio runway in this shimmering wrapped gown. Though internationally renowned, Brazilian supermodel Gisele Bündchen has maintained close connections in her home country — she worked with designer Herchcovitch, modeling his collections throughout the '90s. So when she was called upon for the Olympics opening ceremony, being one of Brazil's biggest celebrities, he would naturally appear a frontrunner to design her Olympics look. How better to show her patriotic streak than with an attention-grabbing silver gown by a Brazilian designer on the biggest sports stage of the season?
