Girls' day out! Caitlyn Jenner takes daughter Kylie for dinner as the teen sports blue lipstick in support of bullying victims

When your lips turn blue after eating under-cooked food, it is normally a cause for concern. 

But thankfully Kylie Jenner's lapis lips were an anti-bullying statement, and not because of the sushi she just ate.

The 18-year-old and her father Caitlyn headed out for a dinner date to Sugarfish in Calabasas on Monday.

Rip up the fashion rule book in Kylie's quirky jeans

Don't Caitlyn and Kylie Jenner make quite the fashionable duo? Both parties were looking on point in the style stakes as they headed out for dinner here, with Caitlyn rocking a lacy skirt (a favored look of hers) and Kylie making us take note of that huge fur coat and unusual light-wash jeans.

When we managed to grab a sneak peak under her oversized outerwear, we could see that the jeans not only had tab appliques at the bottom as well as a whole array of distressed details, but they the words 'WHITE' were printed at the top too.

While they're pretty quirky, so is Kylie and she managed to pull them off in serious style.

Light wash jeans have a certain summery vibe to them, but like Kylie proved here, when temperatures drop, you can easily wear them into the new season by teaming with a big coat, although we'd suggest wearing cute ankle boots to finish the look in a more wintry way than sandals!

As well as her unusual shade of lipstick, the teen wore a long beige faux-fur coat with faded and stressed light blue jeans and a pair of metallic gold heels.

Despite the unusually gloomy Californian weather, Caitlyn stuck with a summerier look.

As well as an almost identical pair of shades to her daughter's, the 65-year-old rocked a pair of strappy white sandals with a short lacey white skirt, and a pale peach long-sleeved top.

Kylie took to Instagram to explain her choice of make-up to her 38million followers.

'Wearing blue lips today in honor of world bullying prevention. #BlueShirtDay2015 #WorldBullyingPreventionDay,' she wrote beneath a selfie of herself and her father.

'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!' she added.

Before the outing, she also gave followers a sneak peek at what she was wearing to dinner, with a below the waist shot along with the caption:  'vibes today for my early dinner with Caitlyn'.

Despite the strong social message of her anti-bullying post, the pic only received 600k likes - far eclipsed by the million likes she got plugging her waist training tool hours beforehand.

Just like her big half-sisters Kim and Khloe, the reality star shared a selfie wearing the waist cynching belt, claiming she wears it around the house before she goes out, and advising anyone 'looking to get a snatched waist or a little help with your posture' to do the same. 

It was clearly a day for showing off her underwear as outerwear, as Kylie also candidly posed in Spanx control underwear. 

Fans suggested that her pert derriere and tiny waist in the shot were thanks to butt implants, but Kylie was quick to tweet details of the nude-hued mid-thigh length underwear.
