Pastels for spring? So passe! Kourtney Kardashian and her two children wore matching all-white ensembles during an Easter morning service at California Community Church in L.A. March 31. The 33-year-old Kourtney & Kim Take Miami star looked fresh in a long-sleeved, floor-length mesh dress, while 8-month-old Penelope sported a floral headband and a Mischka Aoki gown. Mason, 3, paired his ivory shirt and pants with navy blue loafers.

Kourtney's half-sisters, Kendall and Kylie Jenner, selected complementary looks for the family outing. Kendall, 17, looked statuesque in a strapless mint-colored dress and white cardigan sweater, while Kylie, 15, paired her sleeveless white mini with combat boots and a gray knit sweater.

"Just wanted to say happy Easter, and I hope you enjoy your day!" Kendall told her fans in a Keek video. Kourtney also shared several pictures of bunny and chick cupcakes via her Instagram account.

Matriarch Kris Jenner didn't get the family's all-white memo, apparently, given that she rocked a fuchsia dress and sweater combo. "Praise God from whom all blessings flow!" the 57-year-old shared via Instagram. Kris also posted pictures of her family's Easter baskets and her son-in-law Lamar Odom hiding Easter eggs around the yard.
