Twice as Nice: All the Details on North West and Penelope Disick’s Adorable Swimsuits

07/11/2016 at 02:30 PM ET

Penelope Disick and her cousin North West not only share a secret language — they also have a birthday swimsuit style in common!

Kim Kardashian West and Kanye West‘s older child recently turned 3. And in an adorable birthday video posted to her mom’s Instagram account, she’s wearing the tropical Firefly One Piece Bow Back suit by PilyQ.

Weeks later, the daughter of Kourtney Kardashian and Scott Disick sported a similar print by the same brand during her 4th birthday festivities. For her water adventures during a Bahamas boating excursion with her mom, Penelope wore the PilyQ Girls Mix Up Ruffle Bikini in Aloha ($74).

Penelope seems to have taken a leaf out of her mom’s book when it comes to matching outfits. During the same tropical vacation, Kourtney posted photos of herself with two friends, all rocking the same hot-pink one-piece swimsuits.

Her daughter had already previously tapped into the matchy-matchy family style, too — she and Grandma Kris Jenner sported matching lemon-inspired ensembles in early June.

It’s nice to see North smiling. She’s a pretty little girl. I never saw her
smile in pics when she was a baby/toddler.

I basically profit close to $12k-$14k every month doing an online job. For those of you who are prepared to do easy at home jobs for 2h-5h each day at your house and earn valuable paycheck while doing it…

$74 for a swimsuit she’ll probably wear one time! What a waste of money.

And where’s the life jackets? It’s a $75 fine in NH if children don’t have one on at the dock. Safety is more important than a $100 bathing suit! These people are idiots!

North hanging out near the bar. We know girl We know. One day you’ll need it when you find out who you are related to. Poor kid.

Anything to try and stay in the news. Can’t be bothered with the kids any other time.

North is a beautiful little girl. That’s about the only thing I can say nice about this family. And Kourtney seems to be a great mom.
