On Wednesday evening Kenyan time, the whole world was watching as Joe Biden and Kamala Harris were sworn in as US president and vice president.

From the politicians to the celebrities who were invited to witness the auspicious occasion, they knew very well they had to dress the part.

Everyone had to bring their A-game because this was more than the Oscars or the Grammy's red carpet and they knew people would pay close attention to their attires.

Barack and Michelle Obama killed it with their looks as they never let the chilly Washington DC morning kill their vibe.

The former first lady rocked classy purple coat and matching palazo pants that did shout 'I am the iconic Michelle Obama.'

Vice president Kamala Harris also opted for a purple look and her hubby Doug Emhoff who is US' first, second gentleman chose to go for an all black look just like Obama.

Below are the photos which screamed 'Fashionable Americans' at the inauguration;
