Although Coachella celebrates the best in music and art, celebrities who attended the festival also celebrated their siblings in light of National Sibling Day.

The Daily Mail reports that sisters, Paris and Nicky Hilton attended Coachella in matching white outfits and were smiles on Friday which marked the first day of the Festival.

Paris wore an all white outfit consisting of a bikini top and flared skirt while Nicky wore a sweater and skirt.

Sisters, Kendall and Kylie Jenner also attended the festival but chose to wear different outfits that reflected their own personal sense of style, Life and Style reports.

Kylie sported electric teal hair with nude shorts, a crop top, and long vest. Kendall wore high-rise denim shorts, a bikini top and brown vest with a statement necklace, says the Daily Mail.

Both sets of sisters took to Instagram to post in honor of the national holiday and show their attendance at Coachella.

Kylie noted that while she was able to attend Coachella with Kendall, she was missing her eight other siblings who could not make it.
