Meghan took her $2600 Demi tote for a spin on October 3 as she and Prince Harry opened a tech park at a local university, visited a palace, met with youth and more. About 200 fewer individuals were invited to the Duke and Duchess' nuptials.
But when Eugenie arrived, wearing jewellery the exact colour of her mother's dress, Fergie was every inch the proud mother - and the public couldn't get enough of her.
Well, that's all future wedding outfits sorted, then!
Demi, meanwhile, was in good company on Princess Eugenie's big day. In fact, every other wedding guest may as well just turn around now and go home.
Princess Eugenie was the flawless bride on Friday as she married her beau Jack Brooksbank.
Wearing a maroon dress, the famed actress attended the event, as she is friends with Eugenie's parents.
Models Kate Moss and Naomi Campbell as well as singer Ellie Goulding were also among the attendees at Windsor Castle, the venue where Eugenie's cousin Prince Harry and Meghan Markle married in May.
Italian tenor Andrea Bocelli performed during the service led by the Dean of Windsor David Conner.
This is not the first time a new husband has not been given a royal title.
Princess Eugenie and Jack Brooksbank have enjoyed an afternoon reception inside Windsor Castle's St George's Hall organised by the Queen where the 850 guests enjoyed finger food and wedding cake all washed down with Pol Roger champagne.
William and Kate's 5-year-old son, Prince George, served as a page boy, and their daughter, 3-year-old Princess Charlotte, was one of six bridesmaids.
"This is meant to be a family wedding", Eugenie's father Andrew said earlier.
Eugenie is a director at London's Hauser & Wirth art gallery, and Brooksbank owns a wine wholesale business and is European brand manager for Casamigos Tequila, which was co-founded by U.S. actor George Clooney.
Security around Windsor was tight, with airport-style checks and a heavy police presence.
Those lining the streets were unlikely to be royal sceptics, though one watcher was overheard saying that spotting Jeremy Paxman had been the most exciting part of her day.
Born Mary Donaldson in Australia, Princess Mary joined what is perhaps Europe's most popular royal family when she married Frederik, the Crown Prince of Denmark in 2004.
