Those Jenner girls are showing off again!

Today on Instagram, brows and barely there underwear pics were all the rage for Kendall and Kylie Jenner.

New blonde Kylie debuted some lighter brows to match her long and luscious locks. The youngest member of the Kardashian/Jenner clan is documenting each step in her beauty routine into order to keep up with older sister Khloe Kardashian.

"Next step: a haircut by @jenatkinhair and blonde brows by @joycebonelli," the 18-year-old wrote. "I'm shooting my LIVE cover of ELLE Canada today. Follow @ellecanada to help me with me outfits. And check out my snapchat for behind the scenes. #ElleCanadaKylie."

Meanwhile her older sister Kendall stripped down to her skivvies for a day of rest and relaxation. Dressed in only a pink T-shirt and some underwear that look an awful lot like tighty-whities, the model shared a photo of her super-fit body with her fans.

"Bed all day. Rodeo tonight," she captioned the pic.

Earlier this week Kylie used her social media clout to launch an anti-bullying Instagram campaign called "#IAmMoreThan," in which she plans to share stories of people who have taken bullying and turned it into something positive.
