Kylie Jenner just gave #BlueShirtDay2015 a beauty twist! The plump-pouted Keeping Up With the Kardashians star stepped out to dinner with Caitlyn Jenner on Monday, Oct. 5, wearing royal blue lipstick—the hue of World Bullying Prevention Day.

Taking a close-up selfie with Caitlyn and posting it to Instagram, Kylie, 18, wrote, "Wearing blue lips today in honor of world bullying prevention. #BlueShirtDay2015 #WorldBullyingPreventionDay wear blue and post a pic with the hashtags! Spread love & you will receive. Nothing can be done if we don't do it together!"

Kylie's cerulean lips were a bold beauty choice, but they weren't the only memorable part of her look! The rising star, who's been dating rapper Tyga for one year, modeled a furry peach coat, a white tee, and distressed jeans, which she paired with gold heels and a white backpack.

Meanwhile, Caitlyn, 65, took a less bundled-up approach: The transgender icon dined with her daughter while wearing a creamsicle-hued sweater with a lace skirt, accessorized with a brown bag, T-strap sandals, and oversized sunglasses. (Caitlyn also spent some time this week with stepdaughter Kim Kardashian, who posted a photo of the pair via Instagram on Oct. 6, after a particularly explosive episode of I Am Cait on Oct. 4.)

It's no surprise that Kylie shouted out the international support day, as she's been sharing the stories of men and women who have been bullied on her Instagram page, as a way to bring awareness to her fan base. So far, the brunette beauty has spotlighted Lizzie Velasquez (who was cruelly called the "world's ugliest woman" on YouTube), plus-size model Erica Schenk, and Renee DuShane, who suffers from Pfeiffer syndrome, to name a few.
