Katy Perry capped off President Joe Biden’s inauguration in style, belting out “Firework” in a collection of chic separates by New York designer Thom Browne.

The “Never Worn White” singer wore all-white as she closed out a star-studded primetime special, which was hosted by Tom Hanks and had earlier starred performances by Justin Timberlake, Bruce Springsteen and John Legend.

Perry’s outfit comprised a cashmere coat with a corset and floor length skirt, both made from silk satin. She completed the look with deep red lipstick and a pair of heart-shaped diamond earrings.

Against a backdrop of fireworks in the skies over the Capitol, the star’s white ensemble – and signature blonde crop of hair – offered something subtler than the dramatic, exaggerated looks she often sports on red carpets and at high-profile performances like the Superbowl halftime show.

Her choice of color seemingly channeled the symbolism of purity and the suffrage movement, while the red and blue buttons on her skirt and sleeves, respectively, made a delicate nod to the American flag.

Speaking via a label spokesperson, Browne said that Perry looked “sophisticated” and “understated.”

“I wanted her overwhelming talent to be the focus,” he said adding that it was “such an honor to be a small part of this extraordinary day.”

Perry has been seen in Browne’s creations before, most memorably in 2013, when she wore a strapless dress with embroidered roses to the launch of her fragrance, Killer Queen.

But Perry wasn’t the only inauguration attendee dressed by the in-demand designer. On Tuesday, Kamala Harris’ stepdaughter Ella Emhoff posed for a picture at the Capitol in a preppy look by Browne. Pairing an Oxford shirt and tie with a double-breasted coat, she too alluded to American flag colors with a pleated red, white and blue skirt.
