Kate Middleton is known as a modern-era fashion icon and didn't disappoint when she arrived in style at the 11-week-old Prince Louis' christening on Monday.
It was also the first time that Prince William and Kate made a public appearance with all their children, and the family-of-five looked every bit as regal as one would expect.
A short video clip was shared on Kensington Palace's official Twitter account and showed Prince Harry and Meghan walking behind the Duke and Duchess of Cambridge
Kate relied on her tried-and-tested sense of style and chose a cream-colored Alexander McQueen design which featured structured shoulder detail and a modest V-neckline.
It's the same designer Kate turned to for her wedding dress in 2011 and has been spotted wearing the coveted dresses throughout the years. Read more on our Twitter, @amomama_usa.
As reported by People, the style is reminiscent to the white dress and matching hat Kate wore to Princess Charlotte's christening two years ago
Instead of a fascinator, Kate wore a headpiece designed by Jane Taylor. She wore delicate pearl earrings with her hair swept back elegantly. The outfit was completed with champagne-colored high heels.
Since giving birth in April, Kate has only been seen out in public a few times, most notably for Prince Harry and Meghan's rehearsal and wedding back in May.
She also supported Prince William at a recent polo match; the same event where Princess Charlotte tugged at heartstrings when she ran away from her mother.
Earlier today, Prince George and Princess Charlotte were seen holding Prince William's hands, while Kate carried baby Louis. Her sister, Pippa, was also in attendance.
Unfortunately, Queen Elizabeth and Prince Philip did not attend, as the Queen was traveling back from Norfolk and has a busy schedule ahead this week.
She will make an appearance at the RAF celebrations today and will meet with President Trump at Windsor on Friday.
