Happy Bandiversary See Little Mix's 3-Year Style Evolution

It seems like just yesterday Little Mix was formed on X Factor, but today actually marks the 3 year anniversary since Perrie Edwards, Leigh-Anne Pinnock, Jesy Nelson, and Jade Thirlwall came together as a fabulous girl group! Since then, the girls have gone through countless hair colors, fashion trends, and epic tours.

In honor of the girls' big day and Transformation Tuesday, we decided to take a look back at the group's fiercest style moments. We were shocked to see how much they each refined their colorful styles and have turned totally glam lately!
