After last week's high street style-a-thon, the girls and their stylist Frank Strachan pulled out all the fashion stops once again in a host of bargain buys. Here's where to get them!
First to take to the stage was Sam Bailey, who oozed glamour while belting out Adele's 'Make You Feel My Love' for the Love and Heartbreak themed show.
Sam looked hot to trot in a floor-length burgundy gown, £130 from Phase Eight, styling her hair in bouncy curls for added va-va-voom.
Abi Alton was next up, performing her own twist on Kylie's 'Can't Get You Out Of My Head'.
The singer-songwriter hit the style mark in a red cut-out dress, £45 from Topshop, paired with fierce caged heels, £75, available in-store from Miss Selfridge.
Next up was Shelley Smith, who showcased some serious booty-shaking skills while singing Beyoncé's 'Single Ladies'.
The blonde turned heads in a hot pink blazer, £70 from River Island, complete with dazzling shoulder embellishment. She completed her look with coated jeans, £35 from Wallis and a glitzy beaded top, £42 from Topshop.
Tamera Foster set the stage alight with Labrinth's 'Beneath Your Beautiful'.
The 16-year-old upped the ante in a ruby sequin jumpsuit, £350 from Topshop Unique, adding a chic half up, half down 'do and berry lipstick.
Completing our fashion round-up is Hannah Barrett, who wowed with her jaw-dropping performance of Christina Aguilera's 'Beautiful'.
She opted for a monochrome colour palette, rocking a long biker coat from River Island with chunky buckled boots, £34.99 from Heelberry.com.
