Not so mellow yellow! Kylie Jenner and Tyga make for a bold pair as she ditches the glamour in an oversized mustard tracksuit at music party

As one of the most famous teenagers in the world, she's used to having her every move documented.

And Kylie Jenner was unapologetically loud and proud in her appearance as she exited the Migos Listening Party in Los Angeles on Thursday with her beau Tyga.

The reality star, 19, was hard to miss in a bright mustard-coloured tracksuit while the 27-year-old rapper rivalled her eye-catching casual ensemble with a bold orange hoodie.

Be a good sport like Kylie wearing her own collection

Fashion has a new underdog: the humble hoodie. No longer resigned to slobbing round the house, hoodies are being embraced by the fashion elite. We have Vetements to thanks for this hoodie uprising - the label that put streetwear back in the style spotlight.

During fashion week, Vetements hoodies were styled under leather jackets, layered with coats or even paired with thigh high boots.

Even Chanel, renowned for being one of the most elegant couture labels around, got in on the hoodie action for Autumn/Winter '16. So kudos to Kylie Jenner for including one in her latest collection for The Kylie Shop, complete with matching joggers, that both feature the slogan 'thick' emblazoned on them… it hasn’t launched yet but keep an eye out.

If you're used to teaming your hoodie with pyjama bottoms, then it's time to mix things up – get shopping our edit below!

Kylie's baggy attire was worlds away from her usual glamour and one of the rare occasions she had chosen comfort over style. 

The Keeping Up With The Kardashians star swapped her high heels for a pair of black trainers as she kept a tight grip on Tyga while making their way out of the event. 

Always the preened and polished star, Kylie sported her signature coat of make-up, while her hood tamed her glossy raven tresses in place. 

Tyga also put on an attention-grabbing display in a bright hoodie, which he teamed with grey camo trousers.

Updating their followers: The loved-up duo chronicled their night out on Snapchat where social media queen Kylie played around with some fun filters

The father-of-one topped off the look with a funky red and black beanie, while a chunky silver necklace dangled down his front.

The loved-up duo also chronicled their night out on Snapchat where the daughter of Caitlyn and Kris Jenner played around with some fun filters. 

In one snap - which she labelled 'culture' - Kylie sported bunny ears, while the Rack City singer chilled in the background.

She later cut a solo figure for her social media snaps, sporting large doll-like eyes as she pouted to the camera with her purple lipstick.

Love story: The pair first publicly acknowledged they were an item in 2015, after Kylie turned 18, though they'd been a rumoured couple since 2014 (Pictured on Tuesday)

The pair first publicly acknowledged they were an item in 2015, after Kylie turned 18, though they'd been a rumoured couple since 2014.

Though the relationship's not been without its share of difficulty, including a breakup last May that ended in June.

Covering last year's October/November issue of Complex, she revealed: 'The first year we started hanging out, everyone around him told him not to be with me.'

'In fact, I still get comments like: "Don’t be with him." But we’re not doing it for the public - we love each other. 

'We need to be together at all times. We never get mad at each other, we just figure things out.' 

Meanwhile, Kylie is continuing to utilise her Instagram platform - which boasts 83.8 million followers - to plug her Kylie Comestics range.

Fancy: She sported a large diamond sparkler on her left hand ring finger on Thursday as she enjoyed tea

On Wednesday, the star shared two images where she had on very flattering neutral-toned makeup from the successful line while wearing a torn camo shirt.

Giving the camera a faint pout, she let her wavy black hair - which had only last week been platinum blonde - fall free over her shoulders.

This comes just as she shared a Snapchat video of a diamond ring which was worn on her left hand wedding finger while she enjoyed afternoon tea.

In September she flashed a big stone, and went on to clarify that that one had been a 'promise ring', which ignited speculation that she and Tyga were engaged.

However, she refuted all the chatter, by captioning the snap: 'If this is my promise ring I wanna know what my engagement ring gonna look like'.
