The incoming First Lady, 54, opted for a long, tailored navy-blue coat by American designer Adam Lippes, along with a pair of navy-blue suede Manolo Blahnik heels and black leather gloves for the non-partisan service. 

A similar coat is listed on Lippes's website for $4,290.  

Underneath the coat, she wore a white wrap top, adding a pop to the otherwise classic outfit.

However, the real star of the show was a large navy wide-brimmed hat with a flat top and white trimming, designed by Eric Javits - also an American brand.
