Selena Gomez and Taylor Swift are more than just best friends, they also rely on each other for style inspiration!

On Sunday, August 25, the singers attended the 2013 MTV Video Music Awards, where they both rocked head-turning gowns in deep shades of blue.

21-year-old Selena looked mature beyond her years donning an Atelier Versace dress with a thigh-baring slit. Though the long-sleeve gown covered up a lot of her skin, the Best Pop Video winner really played up the sex appeal with an exposed bustier and blood red nails.

Taylor, on the other hand, opted for a more sophisticated approach. The 23-year-old — who picked up the Moonman trophy for Best Female Video — smoldered in a body-hugging number by Hervé Léger.

Always one to put a retro spin on any look, Taylor topped her dress with vintage-inspired pin curls and trademark red lips. Knowing not to compete with the gown's plunging crystal neckline, the “I Knew You Were Trouble” singer skipped a necklace in favor of vampy earrings by Lorraine Schwartz.

Both ladies had jaw-dropping moments on the red carpet, and it’s nearly impossible to choose which look is our fave!

Now we must hand the decision over to you. Selena Gomez or Taylor Swift: who did her navy VMA dress best?
