Kylie Jenner pulled out all the stops to celebrate her 21st birthday on Thursday night, taking her sisters and mother Kris Jenner to dinner at Craig's in LA, before they headed to hotspot Delilah's.
The mother-of-one and beauty mogul looked incredible as she debuted her platinum blonde locks while wearing a stunning magenta dress which had a cut-out detail on the waist.
Having given birth to baby Stormi in February, no doubt she was enjoying a rare night out on the town with her famous family, who dressed in brights to celebrate her special night.
Mixing it up: Her second outfit of the night was a pink sequin strapless unitard which clung to her figure and she wore her locks tied up in a sleek ponytail
Shoulder pads added a retro vibe to her look, while the asymmetrical hem showed off her perfectly sculpted legs.
Delicate magenta ballet-inspired stilettos added a few inches to her 5ft6in frame. Her blonde tresses were parted on the left and surgically combed back and down into a long ponytail.

She carried a perfectly matching bag which was also glitzy and completed her look with pale pink stilettos by Christian Louboutin.
Unsurprisingly, the cosmetics maven's make-up was exquisite, and included a smokey eye, subtle blush and rose-tinted lipstick.
Stormi's father, rapper Travis Scott, 26, kept things very low-key with a white Nike graphic tee as he turned up to help lead the celebrations.

The legal drinking age is 21 in the US, and so Kylie couldn't legally drink until the clock struck midnight as her actual birthday is on the Friday.
While at Delilah's for their private party, the group were treated to the use of a ball pit and had a massive family mural created.
Of course, just about every other Kardashian/Jenner were in attendance. Even queen Kim, 37, took time out of her busy schedule to stop by. Like Kylie, she opted for a pink outfit which showed off her figure in all its glory.

She wore purple strappy sandals and carried her belongings in a clashing see-through bag which gave a glimpse into her belongings as she arrived ahead of her musical artist husband, Kanye West, who was appearing on Jimmy Kimmel.
She later caught up with him and the pair headed in a car to Delilah's together, with Kanye sporting casual cargo pants and a T-shirt for the occasion as he tenderly placed his arm around his wife's waist.
Kim's raven locks were styled into a long and curly hairstyle as she had her extensions back in after recently chopping them off to try out a short bob.
However, she quickly discovered she was not into her new look and swiftly called her hairdresser.

Half-sister Khloe, 34, arrived in a glittering silver co-ord, which showed off her own flat midsection just four months after giving birth to baby True.
Paying close attention to detail, she carried a chic silver clutch bag which had a quilted detail and matched her outfit perfectly.
She also added some inches to her height with a pair of discreet perspex heels - with sister Kourtney offering her a gentle arm of assistance as they prepared to navigate their way up some steps together.

Eldest sister Kourtney, 39, also drew some glances thanks to her shimmering violet number which was suspended by thin spaghetti straps.
The low-cut design showed off her cleavage and her legs looked incredible in the mini, with their dusting of glittery powder which added some further disco fever.
She wore a pair of very high-heeled strappy sandals as she made her way inside, wearing her raven locks up in a high ponytail.
She recently called time on her relationship with boyfriend Younes Bendjima.

Scott kept it casual in a plain green T-shirt, black pants and tan boots.
Kourtney and Scott started dating in 2006 and have eight-year-old son Mason, six-year-old daughter Penelope and three-year-old son Reign together.

She wore a pair of this season's Prada shoes which had a 'fire' design coming out of the back and carried an oversized orange clutch by the label.

Caitlyn, 68, made sure she was dressed for the occasion and slipped into a sequinned mini dress and suede court heels.
Sophia, 22, elongated her honed pins in a pair of studded black strappy heels and, like Caitlyn, she too styled her tresses into perfect curls that sat just past her shoulders.

Her appearance alongside Kylie's father comes after Caitlyn continued to fuel speculation the pair are 'dating' by refusing to address rumours she and Sophia are romantically linked in a new interview with Variety.
Caitlyn addressed her relationship with Sophia, self-confessing the duo are 'inseparable', but wouldn't comment when asked if the pair were romantically involved.
'We are not going to get into that,' the Olympic champion said in response. Although, Caitlyn did add: 'But we are very close. We do a lot of things together.'
'We're inseparable,' she claimed. 'We're the best of friends.'
The former husband of Keeping Up With The Kardashians momager Kris Jenner famously underwent gender reassignment surgery in January 2017 after previously revealing her plans to transition from Bruce to Caitlyn in 2015.

Sophia transitioned while a student at Pepperdine University in Malibu and cited Caitlyn as her role model.
Just last month, the pair attended the ESPY Awards together and in June she opted to attend a charity ball in Vienna, Austria, with Sophia instead of attending her son Brody's wedding.
Caitlyn has grown closer to Sophia amid the distance that's widened between her amid rifts with some of her children and Kardashian step children.
A source previously told Heat Magazine of their relationship: 'Cait really sees herself spending the rest of her life with Sophia.
