Now that we know what FLOTUS and the First Family wore Inauguration Day, we take a look at what the stars donned to mark the historic occasion.

Beginning with Beyonce. 

The singer, who belted her heart out quite melodiously with her rendition of the national anthem, stepped out with her husband Jay-Z in a Washington-worthy, power-packed ensemble. Bey kept warm in a Christian Dior coat draped over her sleeved, floor-length Emilio Pucci gown, worthy of the Inaugural Ball or the Oscars. Her light-colored locks tumbled down to give her overall look a natural but glamorous effect. The star paired her black ensemble with emerald green jewels from Lorraine Schwartz. The glaring green hue is Pantone's color of the year. Bey's other half also brought the fashion factor in a stormy gray Tom Ford suit, light blue shirt, accessorizing his outfit with a pocket square, blue tie and scarf.

Katy Perry, on the other hand, selected a bright orange, striped coat from Rodarte's Fall 2012 collection for the outdoor ceremony. The chanteuse paired her outfit with a black fedora. Boyfriend John Mayer sported a black overcoat, white shirt and light blue tie.

Stars weren't the only ones attracting eyeballs from reporters and fans. Justice Scalia befuddled viewers in his strange hat that channeled Aretha Franklin's odd headpiece in 2009. ABC News reports that Scalia's hat is actually a replica of the one immortalized in an iconic portrait of Thomas More. There's historical significance to the hat, although we're not entirely sure if that's why Scalia opted for this particular style.
