Last night the Saturdays performed a show at the O2 arena to celebrate the first birthday of charity The Transformation Trust, a foundation that focuses on providing extra-curricular activities and opportunities for children in secondary schools as a motivational tool. The concert was free for young people around the country (how jammy is that – maybe I should go back to secondary school and be as lazy as possible to see if I can get into free gigs) and featured other big names on the line-up such as Tinchy Strider, Eliza Doolittle and X-Factor’s Stacey Solomon, who led the crowd in a chorus of “Happy Birthday to you” in honour of the charity.

The Saturdays looked a bit like a girl-band rainbow yesterday, each sporting a super body-con skirt in a different colour teamed up with little white tops to show off their enviable tans. Their white heeled trainers they all sported gave the outfits a cool, sportswear edge on an otherwise hyper-girlie outfit. Check the gallery below to check out what the girls were wearing, and pieces you can find to copy their look.
