Princess Eugenie Steps Out for the First Time Since Giving Birth on the Red Carpet with Sister Princess Beatrice

Prince Andrew and Sarah Ferguson's daughters made separate entrances at the Vogue World bash

Princess Eugenie and Princess Beatrice are making a fashion statement!

On Thursday, the daughters of Prince Andrew and Sarah Ferguson hit the red carpet at Vogue World: London 2023 at the Theatre Royal Drury Lane in London.

Princess Eugenie, 33, stepped out solo in a draped satin teal Fendi gown with sparkly shoes for her first public appearance since giving birth to son Ernest George Ronnie in May.

Princess Beatrice, 35, walked the carpet with her husband, Edoardo Mapelli Mozzi. She wore a black and yellow floral cape dress by Richard Quinn with black gloves and heels, while Edo sported a tux with a white jacket.

The second annual Vogue World kicks off London Fashion Week and welcomes guests to “experience a host of performances from leaders across the entertainment world, culminating with a live runway show with models wearing highlights from the fall 2023 collections,” Vogue said in a statement, summarizing the fun as an “ode to Britain’s rich culture.”

The night is especially momentous for Princess Eugenie, as it marked her first red carpet since welcoming her second baby with her husband, Jack Brooksbank. In May, they became a family of four when she welcomed Ernest, making their 2-year-old son August a big brother.

Eugenie’s last major public outing was King Charles’ coronation and related celebrations for the May 6 crowning, including a Coronation Big Lunch in Chalfont St. Giles and the Coronation Concert at Windsor Castle.

Baby Ernest was born on May 30, and Princess Eugenie was there for her mother, the Duchess of York, when she was diagnosed with breast cancer. The Duchess of York, who is popularly known as Fergie, successfully underwent a single mastectomy and was visited by Eugenie and Beatrice as she rested up at Royal Lodge.

“Her daughters have been there a lot, they have been very supportive,” a source told PEOPLE in June.

Princess Beatrice had a very social summer with her husband Edo, and they seem to be continuing the festivities into the fall. On Wednesday, the couple checked out the new “Gabrielle Chanel. Fashion Manifesto” exhibit at the Victoria & Albert Museum in London. Beatrice accessorized with something special and wore a gold necklace with her husband, daughter and stepson’s initials.

Featuring charms on a long chain, the tribute to her loved ones featured an “E” for Edo, an “S” for their daughter Sienna Elizabeth, who turns 2 next week, and a “W” for Wolfie, the affectionate nickname for Edo’s young son Christopher Woolf, who he shares with his ex-girlfriend Dara Huang.

Princess Beatrice has worn the charm necklace before and becomes the second royal mom to accessorize with her kids’ initials this week.

On Tuesday, Kate Middleton visited HMP High Down, a men’s prison in Surrey, England, and wore her customized Gold Midnight Moon necklace from Daniella Draper. The circular charm features the initials of her children’s names and keeps Prince George, 10, Princess Charlotte, 8, and Prince Louis, 5, close to heart.

"It's a piece that I designed with myself in mind,” the designer previously told PEOPLE. "I wear it every day, as does my mom and sister. It's becoming one of our best sellers and it can be personalized in so many ways."

Next week, Beatrice will celebrate a special occasion — Sienna’s birthday! Sienna turns 2 on Sept. 18, and Fergie opened up about how she’s growing up fast during an August episode of her podcast Tea Talks with the Duchess and Sarah.

"Beatrice and Edo are away so Gee Gee is in charge, and it's really quite amusing,” Fergie, 63, told her co-host Sarah Thomson of the fun she had babysitting. “I wished for the time that Sienna would come in and say, 'Gee Gee come and play,' and now every minute of the day Sisi wants to come and play!" she laughed, using her granddaughter’s nickname.

“Be careful what you wish for 'cause now you can’t even have a moment to sort of do anything without this wonderful little girl, who is so sweet, pulling at my skirt, jumping into my Ugg boots and then making me go outside in the pouring rain and jump in puddles in the pouring rain — which is fine, I love it,” she said.
