When it comes to Kristen Stewart vs. Riley Keough, Robert Pattinson isn't the only element involved. The "Runaways" actresses seem to have a similar sense of style.

For Kristen Stewart, shorts, sheer lace, and leather are her favoured garments. It just so happens that Riley Keough goes for the same type of clothing.

In July, Kristen Stewart jetted to Paris to watch Uncle Karl's latest couture collection for Chanel. The 23-year-old showed her love for shorts when she took her front row seat in a black pair, with a white Chanel jacket, fingerless gloves, and Jean-Michel Cazabat heels.

While Kristen's riff on classic Chanel was a win, Riley opted for Victorian on top, hipster on bottom during the "Mistaken for Strangers" premiere at the Tribeca Film Festival in April, 2013. Elvis' grand daughter paired a frilly Wes Gordon lace blouse with yellow Jenny Kao shorts, and nude Louboutin pumps. It wasn't an instant hit, but Riley's outfit did have a certain charm.

It was one screening after another for Kristen Stewart. "On the Road" had the actress swapping outfits every so often. A lot of Kristen's "On the Road" promotions wardrobe was made up of sheer looks. One of those sheer outfits was her Catherine Malandrino dress in December of 2012. Kristen picked a long-sleeved number with alternating sheer and beaded stripes. It was a striking dress that revealed quite a lot of Kristen's figure. With all the effort she put in her sparkling outfit, Kristen could have taken the extra step and worn something other than black pumps and a lackluster hairstyle.

Riley Keough's answer to Kristen Stewart's sheer dress was her Rachel Comey outfit at the "Jack and Diane" premiere in 2012. Riley smouldered in her subtly glittering, black dress with a sheer yoke and hem. Unfortunately, Riley did a Kristen and paired her dress with black pumps. Even worse, the "Mad Max: Fury Road" star wore a long sweater that concealed most of her dress.

The Kristen Stewart vs. Riley Keough style battle continued with Kristen's leather look at another "On the Road" screening. She looked sleek and sassy in a BCBG blazer, H&M leather leggings, and standout red pumps.

Riley Keough out-leathered Kristen's leather look when she posed for her Tribeca Film Festival portraits in April of 2012. She took her ALC leather pants to the next level by mixing it up and pairing it with a floral Rachel Roy top and gold Christian Louboutin peep-toes.

Shorts, sheer, and leather share common ground in their closets, but start the slideshow to see who wins in a Kristen Stewart vs. Riley Keough style battle.
