The four singers - minus pregnant Frankie Sandford who is on maternity leave - mixed colourful animal prints with cute fringed detail and even flashed their bras at a thrilled audience!
New mum Rochelle Humes was the only Saturdays member to cover up in a cropped leather jacket, worn over a brilliant yellow vest and red and purple printed skirt.
Wearing contrasting colours, Una clashed her red hair with a scarlet top and tassled skirt which showed off her stunning legs!
Mollie, meanwhile, flashed the flesh in a fuchsia bra, glimpsed under a yellow tassled vest which she wore with a red and pink mini skirt.
Vanessa's curvy body was flaunted in a black vest, worn over a red bra, with cute orange and blue-patterned skirt.
All four girls wore towering black heels as they performed some of their famous hits on stage.
After their energetic set, the girls tweeted a message to the event organisers from their official Twitter account.
They said: "#PartyAtThePier Liverpool you rocked!! Thanks to @Juice_FM for having us!"
