Cheryl Cole and Jessie J made a style stand at the Capital FM Summertime Ball this weekend.
After a bland backstage shift dress, Cheryl transformed into a 70s queen with a multicoloured striped catsuit.
Jessie J however went an era ahead with her polka dot shorts and motif tee that gave a huge nod to the 80s.
Also making an appearance was Katy Perry who also showed off the polka dot look in a 50s inspired trouser and crop top outfit, while new face Carly Rae Jepsen played it safe in a sequined dress.
See the gallery below for all the star style.
