Another batch of eager hopefuls arrive for X Factor boot camp in the hope of becoming the UK's next big thing

These are the host of hopefuls who arrived at boot camp for the second day of filming for this year's X Factor.
And this year may be the brightest we've seen yet as a number of contestants turned up in an array of neon yellows and pinks.
Every year hopefuls make an attempt to stand out in whatever way they can, but the judges may find it hard to forget some of these artists' style choices.

Dressed to impress: This band looked color-coordinated in neon yellow, green, denim jackets and white shoes

Eye-catching: This band would certainly be sure to catch the judge's attention in these ensembles

Hoping to shine: One girl (left) opted for a bright yellow dress with purple and green swirls and gold shoes, and (right) another sing hopes to stand out in a turquoise, black and gold top

Although there a hundreds of new auditionees, this year's show will also see a host of former contestants return to our screens for a shot at stardom.
Several rejects decided to re-audition, including last year's boy band, Rough Copy, girl band Dolly Rockers from 2006, solo artist Terry Winstanley from 2011 and singer-songwriter Amy Mottram who wowed the judges last year.
Boy band Rough Copy were forced off the show last year after Nigerian-born Kazeem Ajobe didn't get a visa in time to travel to judge Louis Walsh's Las Vegas home.

The colour continues: Even more bright ensembles, with one girl wearing a bright orange dress and another woman in an eye-catching Egyptian-style dress with a gold headdress

Even more colour: The parade of colour just did not stop with one girl (left) in a stunning floor-length orange gown and sparkly boots and another male singer (right) in a bright red T-shirt

Girl band Dolly Rockers, who first made an appearance on the show in 2006, have also tried their luck again, winning a place at Boot Camp following last week's Wembley Arena auditions. 
Several solo artists are also bidding for success on the show again, including Terry Winstanley, who got through to Judges Houses in 2011 but failed to progress to the live finals.
A source told The Sun newspaper: 'There have been so many recognisable faces on this year's show it's turned into something of a 'best of the rejects' special.
'It'll be extremely frustrating to people not given the chance to see someone who has already had a crack at it go through again.'

 

Beautiful in blue: Nicole Scherzinger spotted on day two of bootcamp in a powder blue cut-out dress, despite not being ready for the camera (left)

Another day of filming: Nicole and Louis chatted away as they left the studio together on the second boot camp day

A noticeable change from the last series is the introduction of popular celebrity judge Sharon Osbourne, who has taken the place of Tulisa Contostavlos.
The 60-year-old businesswoman, music manager and wife of heavy metal singer-songwriter Ozzy Osbourne was one of the original four judges on the X Factor from 2004 to 2007.
She joins Nicole Scherzinger, Gary Barlow and Louis Walsh as the foursome who will be putting the hopefuls through their paces.

Back in the game: Sharon doing what she does does best as she guides people around for the second day of boot camp

Nicole, 35, looked stunning in a pale blue cut out dress and beige stiletto heels with a gold clasp whilst fixing her hair into two French plaits.
Sharon appeared equally as stylish for filming dressed in a pair of black trousers, black top, white jacket and a long Chanel beaded necklace.
Gary and Louis also didn't disappoint with Gary in a fitted petrol blue shirt and Louis in a fetching pink shirt.

Head judge: Gary Barlow was also spotted at the boot camp, making this year his third year as head judge taking over from Simon Cowell

She's back too: Caroline Flack was dressed in a cream and black striped short skirt, black top and chunky heels on set, and she even had time to put a few small braids in her hair

Dressed up: Another pair of hopefuls waiting to know if they have made it to the live shows were wearing slightly different outfits, one in a leopard print 50s style dress, the other in a more 90s inspired print dress

Punk rock: Two girls who didn't wear much colour opted for a more punk rock look as they carried their suitcases to the studio

Girl power: More soloists arrive for their auditions with one (left) in a fitted print dress and pumps whilst another (right) in a more casual blue top, jeans and pink trainers

We're ready: The boys were certainly making an impression too, one guy (left) wore a denim shirt, ripped black jeans, Timberland boots and a gold chain whilst another (right) decided on an Armani belt, black trousers, Converse trainers and a white jumper

Style parade: The guys certainly came out in their best gear this year, one hopeful (left) wearing a black bomber jacket, cropped chino pants, Converse and a hat spelling the name 'Shane' whereas (right) a guy wore a trilby hat, black suit jacket, black trousers and trainers
