It has been nearly a decade since Little Mix won X Factor and the girls show no sign of slowing down.
Five albums and countless tours later, Perrie Edwards , Leigh-Anne Pinnock, Jade Thirlwall and Jesy Nelson have grown musically and become an established force of the pop world in the UK and the world.
But it is not just their songs that have matured and changed over the years, they have also refined their look and there has been a dramatic change in how they looked when they stood on stage with mentor Tulisa Contostavlos in 2011.
Gone are the bright eyes-shadows and baby pink lipsticks.
Instead, the popstars now opts for lip-plumping matte lipsticks with lashings of 90-inspired liner.
Some of the band-mates have delved into designing clothes, Leigh-Anne has her In 'A' Seashell luxury swim-wear range, And Perrie tried her hand at developing a line of shoes with Superga.
When Perrie, girlfriend to Liverpool player Alex Oxlade-Chamberlain , first started hitting the red carpet she preferred a relaxed bohemian-style.
With denim shorts, headbands and hats, Perrie loved the festival look, at one point even dying her hair lilac.
By 2013 she had taken on a bit more of a grunge fashion style, with plaid shirts and chunky, black boots for performances - but she and her fellow singers took awards shows more seriously opting for sleek, sexy dresses and heels.
Her developing style echoed the other girls in the band who, after two years in the industry, were learning just how to pose on the red carpet.
Through this period, Perrie, 26, had been dating One Direction's Zayn Malik, and the couple seemed very much in love, getting engaged in August 2013.
But they spilt in 2015, leaving Perrie heartbroken.
This massive shift for the girls sparked a new, empowered style of music, performance and fashion as they looked towards their fourth studio album 'Glory Days' in 2016 featuring the song 'Shout Out to my Ex', which many speculated was aimed at Zayn.
Now opting for skin-tight body suits and thigh-high leotards, the band's new sexy style caught the eye of TV viewers when they went back to X Factor when they were blasted by some who said their revealing clothes made them look like "prostitutes and strippers".
Little Mix shocked viewers by wearing black blazers and trousers during the first part of their performance, but 'inevitably' they stripped to reveal their bodies during their 2017 performance.
But, the girls didn't change their costume choices, even making hitting back with a strong message in 2018 when promoting their new single 'Strip'.
Little Mix have shared an image of themselves stripped naked with insults written all over their bodies.
The black and white photograph shared on Instagram shows the singers sat on the floor and coiled around each other so that their modesty is protected.
Perrie was pictured with the words 'ugly', 'stupid' and 'weak' on her body.
It was accompanied by a body positive message which is thought to have been taken from the new song.
The post said: "Take off all my makeup cos I love what's under it.
"Rub off all your words don't give a f*** I'm over it.
"Jiggle all this weight, yeah you know I love all of this
"Finally love me naked, sexiest when I'm confident."
They also thanked women of all shapes and sizes for taking part in their new music video for Strip.
On their official Instagram account, they said: "Strip is a really special song from LM5, it’s all about standing proud and we wrote it to encourage and empower people to be who they are."
It continued: "Thank you for being part of this incredible journey with us.
"#LM5 featuring #Strip is coming Friday 16.11.18."
Perrie regularly posts snaps on Instagram of her fresh, holiday looks showing off her enviable toned abs and loved-up pictures with Alex, who she has been dating since 2017.
Currently sporting platinum blonde locks, Perrie's make-up is always social media-ready with perfect brows and muted lip tines from a natural palette.
And Perrie isn't the only one who has undergone a style overhaul.
In the last decade, Jesy has ditched the baggy layers - and adopted the flesh-baring outfits of her bandmates.
Now, she opts for risqué high-legged bodysuits and push-up bras to flaunt her toned dancers' figure.
She's also a dab hand with a contour brush, chiselling her cheekbones with blusher and using highlighter to accentuate her slim nose.
And the 28-year-old has spoken candidly about her body issues in a recent BBC documentary Jesy Nelson: Odd One Out.
Jessy revealed how she tried to take her own life after suffering vile abuse from online trolls.
The singer said she became almost "obsessed" with reading negative comments about herself after she found fame on the X Factor in 2011.
The Guardian quoted her as saying last year: "It only got worse when I got Twitter. And that led to the Daily Mail, and reading the [below the line] comments - the worst you can read about yourself.
"It was like I purposely wanted to hurt myself."
"I had a routine of waking up, going on Twitter, searching for the worst things I could about myself.
"I'd type in the search bar, 'Jesy fat', or 'Jesy ugly', and see what would come up. Sometimes I didn't even need to do that, I'd just write 'Jesy' and then I'd see all the horrible things.
"Everyone told me to ignore it - but it was like an addiction."
Speaking about her struggles on BBC One documentary , Jesy said she would starve herself before TV performances or video shoots, then later binge eat.
Her lowest point came after Little Mix returned to the X Factor in 2013 and Nelson's appearance again drew criticism, and the singer tried to kill herself.
She said: "I felt that I physically couldn't tolerate the pain any more."
Things started to change the following year when Little Mix toured with US star Demi Lovato and some of Lovato's dancers suggested Jesy come off Twitter.
She said: "It was a long, hard process, because I didn't want to help myself.
"But it wasn't until I deleted Twitter that everything changed for me and I slowly started to feel normal again."
Nelson said while she still has bad days, "instead of beating myself up about it and being miserable, I think, 'OK, I'm going to have my moment of being sad, and I'll be over it'."
She added: "Before, I didn't let myself be sad."
