The girls ditched their signature street-cool style in favour of fabulous frocks as they attended the Attitude Awards.
With cut-out panels, embellishment and demure draping, we're loving the ladies' latest looks.
And their locks were transformed too!
While Jesy rocked her trademark mega-quiff (find out how to copy it here!) the other Little Mixers sported sophisticated up-dos.
Jesy showed off her enviable curves in a mullet-hem dress, £19.99, from Missguided paired with heels, £149.99, by Kandee Shoes.
And Jade opted for an embellished LBD, £89, from Miss Selfridge - we're coveting this for the party season!
Leigh-Anne showed off her perfect pins in this thigh-split maxi dress, £194, from Gorgeous Couture while Perrie dazzled in a blue knee-length dress, £189, also by Gorgeous Couture.
