Sheer sex appeal! The Saturdays step up their attempt to take over the States as they don see-through tops

It's certainly one way to grab America's attention.
The Saturdays stepped out in New York on Thursday giving onlookers a glimpse of their underwear.
Mollie King, Vanessa White, Frankie Sandford and Una Healy donned sheer clothing as they did the promotional rounds. Only pregnant singer Rochelle Wiseman covered up, in an eye-catching geometric dress.

Eye-candy: The Saturdays appeared at the NBC studios in New York City on Thursday

They may have been doing radio but the ladies made sure they gave the hosts something to speak about as well as of course providing some eye candy for fans waiting outside of the SiriusXM studios.

The group’s only single member Mollie, wore a silver crochet crop top which allowed her black bra to be seen underneath. She teamed it with a foil-like pleated miniskirt and left her blonde locks hanging loose.
Redhead Una – who is married to rugby player Ben Foden and has a 10-month-old daughter – wore a black glittered frock with deep V-neck which featured a mesh panel around her bust.

Frankie – who sports a pixie haircut - fashioned a shiny round-neck top where her undergarments could be seen and she teamed it with a fitted skirt.
And Vanessa was perhaps the most risqué with her ensemble; it featured a long denim skirt with chunky studded belt as well as a sheer top which allowed her bra to be visible.
The ringlet-haired singer covered up a bit with a leather jacket and added staggeringly high heels and a large heart necklace to match the coat.

Mother-to-be Rochelle kept it classy in a black and white fitted dress which almost disguised her bump with its clever patterns.
The stars also attended an autograph signing at the NBC Experience Store at Rockefeller center in NYC. 
The day before the Saturdays revealed they are trying to find Mollie a ‘prince’ but they don’t man a royal for the 25-year-old.

Speaking on The Today Show Rochelle, 23, told host Willie Geist: ‘We're trying to find [Mollie] a prince, but not necessarily a royal one.’
Although there were rumours last year that Mollie was enjoying dates with Britain's Prince Harry, the singer dismissed the idea that she and the fourth-in-line to the throne were any more than friends. 
She explained: ‘We're friends and we have friends in common but it's a rumour that just spiralled out of control. The girls are always trying to set me up!’

Una, 31, has left family back home in the UK while she and the girls promote their new reality show Chasing The Saturdays in the States and she admitted it can get difficult being apart for so long.
Recalling when the girls left for Los Angeles last summer to film their programme, Una said: ‘It's very difficult being away from my husband because we were newlyweds when we came out to Los Angeles. 
‘He's very understanding and his job as a professional rugby player takes him away a lot, so it kind of keeps things fresh.’

Pregnant Rochelle is also currently away from her husband - JLS hunk Marvin Humes - confessing: 'I'm sort of finding out [about motherhood] as I go along.'
Frankie, 24, confessed the girls were ‘nervous’ when first surrounded by the cameras, but soon adapted and enjoyed themselves.
She said: ‘When we first started out we were a bit nervous. It's hard to get used to for the first couple of days but you seriously forget they're there.’
