Princess Eugenie shared a cute throwback photo with her sister Princess Eugenie and mom Sarah Ferguson.

The youngest Princess of York took to Instagram and shared an adorable photo of what she described as “classic twinning” with her older sister. In the snap, both are wearing white t-shirts and gingham skorts printed with sunflowers. They also wear matching yellow boots.

A number of fans were so delighted to see the photos and praised it. They found Prince Andrew and Ferguson’s daughters “beautiful.”

However, more noticed Princess Eugenie’s mom’s fashion. In the photos, Ferguson wears a white shirt, black polkadot skirt, denim jacket and white sneakers. She also accessorized with dark shades and a silver necklace.

One netizen said that Ferguson “looks so cool” in the photo. Another described the Duchess of York’s outfit “fab.” Meanwhile, a number said that they would wear Ferguson’s outfit today if they have the chance.

“I would wear Sarah, Duchess of York's outfit today!” one fan commented.

“I mean, the sunflower skirt is great, but I'd wear your mom's outfit right now in a heartbeat,” a different user wrote.

“Feel like her outfit is very “in” right now lol,” another user said about Ferguson’s outfit.

In related news, there are rumors that Princess Eugenie is pregnant. Royal fans are waiting for her baby announcement after she was spotted with what appeared to be like a baby bump.

Princess Eugenie skipped the royal family’s reunion on Easter Sunday which also happened to be Queen Elizabeth II’s birthday. However, she accompanied Her Majesty on Maundy Thursday.

Princess Eugenie stepped out in floral dress for the said outing. However, in some side view photos, her stomach appeared to be bigger than usual.

Earlier this year, Alex Apati of Ladbrokes said that the royals are getting broody. He added that among the married royals, Princess Eugenie is the most likely to make a baby announcement after Prince Harry and Meghan Markle.

There are also speculations that Ferguson has already confirmed her daughter’s pregnancy in one post on Instagram. On Easter Sunday, the Duchess of York shared a snap of yellow cake which is the preferred gender-neutral color for baby celebration cakes.
