Everyone loves a good fashion faceoff, but sometimes the celebrities rocking the same outfit aren’t two supermodels, or two best friends, or both, in the case of Gigi Hadid and Kendall Jenner.

Sometimes the stars facing off are a more surprising twosome – and yet, they both look so good it can still be too tough to call who wore it best. Here are some of the most unusual fashion faceoffs…

Paris Hilton vs. Kate Middleton – One is the original princess of reality TV, the other is a real-life Duchess. And yet somehow, despite their normally different styles they both look positively regal in this white Self Portrait gown.

Kris Jenner vs. Justin Bieber – It turns out that all along, Kris Jenner’s real style icon has been fellow Balmain favorite, Justin Bieber. (I honestly cannot decide who wore it better.)

January Jones vs. Suki Waterhouse – Whether your style is prim and proper or boho chic, one thing’s for sure… NOBODY can possibly resist a printed bomber jacket!

Rihanna vs. Julia Roberts – It takes a very brave soul to rock a dress originally worn by Rihanna, but Julia Roberts did an amazing job! It becomes slightly less risky when it’s fully lined, which is the route that Roberts took when she wore this Gucci dress.

Aubrey Plaza vs. Erika Jayne – This fashion faceoff has taught me two key things: Both of these women have amazing legs and we need to see Aubrey Plaza join the cast of Real Housewives of Beverly Hills.

Paris Hilton vs. Carrie Underwood – Because a sparkly gold fringed dress is perfect for every occasion, whether you’re a socialite or a country music goddess.
