Rihanna and Miley Cyrus show off risqué style at amfAR gala

Few celebrities have mastered the art of shock and awe on the red carpet quite like Rihanna and Miley Cyrus. At the amfAR Inspiration Gala in Los Angeles on Wednesday night, the two singers stepped out in minimalist looks — meaning minimal skin was covered.

While most in attendance at the formal charity event dressed more conservatively, Rihanna and Miley opted to show some skin in their scantily-clad outfits. The 26-year-old "Diamonds" singer smoldered in a flowing white dress with a slit that showed off thigh-high stockings and a see-through bodice with strategically placed purple beading.

The look was more covered up than some of Rihanna's past red carpet outfits, which include a completely see-through beaded dress at the CFDA Awards in June and at the 2011 Grammy Awards, when she arrived in a floor-length peek-a-boo gown.

Miley, who wears a wardrobe of leotards on her worldwide tour, showed up in a black ensemble with a long skirt that was less covered-up on top. The bondage-inspired bodice bared lots of cleavage and a few black strips of fabric to conceal a tad of modesty.

The pop star, 21, attended the charity event with her mother, Tish Cyrus, who wore a slinky silver V-neck gown. The mother-daughter duo both wore dramatic black eye makeup and styled their hair in a deep side part. Tish, 47, mimicking Frozen's Elsa, opted for a stylish side braid.
