For her first day as first lady, Melania Trump opted for a Jackie O-channeling look from a classic American brand.

Melania debuted her Tiffany-blue inauguration outfit on Friday morning, wearing a custom Ralph Lauren ensemble as she and Donald Trump arrived for a church service at St. John’s Episcopal Church across from the White House.

Melania's ensemble consists of a cashmere cropped jacket and mock turtleneck dress, suede gloves and a suede clutch, all in sky blue. In a departure from her usual shoulder-sweeping blowout, she wore her hair in an updo.

Her icy blue rounded out Donald Trump's patriotic red and white ensemble, with the Obamas also sporting the colors of the flag as the two families met at the White House.

Melania also arrived with a gift that matched her dress, handing Michelle Obama what looked like a Tiffany's box as she greeted the outgoing First Lady on the steps.

The other two Trump women opted for white, with Ivanka appearing in an asymmetrical jacket, reportedly by Oscar de la Renta, and Tiffany wearing a full-length, double-breasted coat.

While the Trumps opted for subtle patriotism in their fashion choices, Kellyanne Conway went full Revolutionary War with her eye-popping $3,600 Gucci coat.

Now, that's a look.

Fashion-watchers have speculated which designers Melania would wear for the inaugural festivities. . Lauren A. Rothman, stylist and author of Style Bible: What to Wear to Work, foresaw Melania's daytime look in an interview with USA TODAY, predicting the first lady would opt for a professional look.

"It would be great if she wore a classic dress that any woman could slip into," she said, advising Melania to wear "items that can lend an executive presence."
