Happy International Siblings Day, everyone! For those of you lucky enough to have a brother or a sister, now’s the time to plaster super embarrassing photos of him or her all over Instagram. When you’re finished with that, go track down your sib and give them a noogie, a wet willy, and a wedgie. Ahhh, memories to last a lifetime! Only children, you guys can get in on the fun by popping open a bottle of champagne with your parents and thanking them for #blessing you with a life of nonstop, undivided attention.

And when we’ve all had our fill of wedgies and champagne, come on back here to check out the following roundup of the 15 most fashionable celebrity siblings. These brother and sister pairs prove that great style is all in the genes.

1. Beyonce and Solange Knowles

It’s no secret around these parts that we idolize Solange Knowles for her personal style, and Queen Bey needs no introduction. These two sisters have their mother, Tina Knowles, to thank for their incredible fashion sense–Tina was the mastermind behind the outfits that helped make Destiny’s Child so famous.

2. Kate and Pippa Middleton

The Middleton sisters are responsible for one of the most iconic fashion moments of the decade. Kate’s wedding gown and Pippa’s bridesmaid dress, both designed by Alexander McQueen’s Sarah Burton, will live on forever in #WeddingInspo lore.

3. Gianni and Donatella Versace

Gianni Versace was the founder and creative genius behind Versace until his tragic and untimely death in 1997. Following the passing of her brother, Donatella took over the label and continued his legacy as “the king of fashion.” 

4. Jaden and Willow Smith

There is absolutely no doubt in my mind that these two are going to look back on pictures of themselves one day and wonder what the hell they were thinking, but even I can’t deny that the Smith sibs have a signature style all their own.

5. Jackie, Tito, Jermaine. Marlon, and Michael Jackson

You can’t talk about ’70s style without mentioning the Jackson 5. Brothers Jackie, Tito, Jermaine. Marlon, and the late Michael rocked matching jumpsuits like none other.

6. Dakota and Elle Fanning

Both Fanning sisters have had impressive acting careers, and, dare I say it, even more impressive wardrobes. Big sister Dakota is the face of Marc Jacobs’ Oh, Lola! perfume, and Elle has modeled for W, Vogue, and Italian Vanity Fair, and was the face of Miu Miu’s spring 2014 collection.

7. Brooklyn, Romeo, and Cruz Beckham (and little sister Harper!)

The Beckham brothers have their super fashionable parents, Victoria and David, to thank for their impeccable style. Of course, I’d be remiss if I didn’t mention little sister Harper, who may be only three years old but is already a style icon among the toddler set.

8. Serena and Venus Williams

I’ve long admired Venus and Serena Williams for their ability to show off their personal style even when they’re battling for titles on the tennis court. Last summer I watched Venus Williams kick ass at the Canadian Open, and let me tell you, she was hands-down the most glamorous woman in the stadium. I think it’s safe to say that we have Venus and Serena to thank, at least partially, for the push in athletic wear as street wear.

9. Dean and Dan Caten

Dean and Dan Caten are the identical twin brothers behind the label DSquared2. They make the list not only because they’re internationally adored designers, but also because they always dress alike. Identical twins who dress the same are my favorite people on Earth. I mean, how cute do they look in those impeccably tailored suits?

10. Kourtney, Kim, and Khloe Kardashian, and Kendall and Kylie Jenner

Even if the Kardashian-Jenner sisters aren’t your cup of tea, you can’t deny that these girls each have their own incredible sense of style. Also, can we talk for one second about the fact that the human on the far left in this photo is Kylie Jenner? Honestly, if Getty Images didn’t label the photo, I’d think she was a Kardashian kousin.

11. Poppy, Cara, and Chloe Delevingne

While you’ve undoubtedly heard of British model Cara Delevingne–she’s Karl Lagerfeld’s latest muse, so she’s everywhere–it may come as a surprise to you that she has two older sisters who are just as fashionable as she is. While they aren’t household names on this side of the pond, Poppy and and Chloe have both attained fashion icon status in their native England.

12. Liesl, Friederich, Louisa, Curt, Brigitta, Marta, and Gretl von Trapp

OK, I know that these people are not the real von Trapp siblings, but I just couldn’t leave them off the list. And don’t even try to tell me that you weren’t tempted to wear your curtains as clothing after you watched the von Trapp children spin around Austria in theirs. Also, love those pleated skirts. Very on trend!

13. Mary-Kate and Ashley Olsen

I know that Mary-Kate and Ashley are only 28 years old, but I don’t think it’s too early to say that they are the most stylish siblings of all time. Maybe I’m biased because they’ve been my style icons since their Full House days–seriously, baby Michelle had style. The twins have come a long, long way from their days hanging with John Stamos in San Francisco. They are now the creative geniuses behind luxury labels The Row and Elizabeth and James.

14. Gigi and Bella Hadid

Bella and Gigi are the daughters of retired supermodel and current Real Housewife Yolanda Foster. While these two are fairly new on the modeling circuit, a quick scan of their Instagram accounts will convince you that they are both about to be the biggest things in fashion.

15. Paris and Nicky Hilton

Don’t roll your eyes at me! I know the name “Paris Hilton” invokes images of Von Dutch Hats, denim mini skirts, and pink stilettos, but trust me, this heiress has come a long, long way from her Simple Life days. And as for Nicky? Well, she’s always had style.
