We thought the rule was: never wear a black bra under white. Apparently that's all out the window now as Selena Gomez rocked the trend on the first day of the 2014 Coachella Festival in California.
The 21-year-old actress donned a 70s chic flower power long lace sheer dress, which she wore with white shorts and black underwear beneath.
She finished with a cool felt hat, heavy, edgy boots and a slick of bright red lippie.
The star attended the festival with the Kylie and Kendall Jenner, who both looked stunning in super-short shorts. But Kendall took her look a little further and worked a cool cape-cardie thing over her high-waisted denim, which she enhanced with a cute waist belt.
She finished her look with mirrored aviators, large necklaces, and cowboy boots, and pretty much looked the top model that she is.
Kylie, meanwhile, looked trendy in her David Bowie top and black cut-offs, and also seemed to be bringing back the bumbag with a fashionable studded version.
Her dip-dyed blonde locks could be seen underneath her beige felt hat, and she also worked round celeb-worthy shades.
Coachella - pretty much known as the coolest festival going thanks to its young Hollywood attendees and hot, mud-free thang - runs over two weekends, 11 to 13 April, and 18 to 20 April.
Headliners include Pharrell Williams, Landa Del Rey, Fatboy Slim, Lorde and Outkast.
