The Saturdays celebrated their single 'What About Us' hitting No. 1 in the U.K. by showing off lots of leg in pretty party dresses. The girls hit up the BBC Radio One Studios, enjoying their big "get" by getting all dressed up. 

The girls showed off their unique style in a variety of dresses in different cuts and colors. The only consistent element? That they showed lots and lots of legginess.

Mollie King was a vision in white, wearing a sleeveless dress paired with tan heels.

The pregnant Wiseman was cute as a button in her black, somewhat sheer dress with Peter Pan collar. It appropriate for her condition without losing ANY style points.

Sassy Frankie Sandford also looked adorable in a two-piece, with a white top and a silver skirt.

Redheaded Una Healy was the lone Saturday to demonstrate an affinity for color in her purplish two-piece look, which showed a bit of her abdomen.

While Vanessa White was dolled up in basic black, which gave us a view of her twins, she carried a major clutch that looked like an iPad case. What ya got in there, girl? Her majorly strappy heels were the preferred accessory.
