St Trinian's 2 Premiere: Sarah Harding stunning black sequin gown & Nicola Roberts in Georges Chakra

Check out the high glamour that is Girls Aloud at the world premiere of St Trinian's 2: The Legend Of Fritton's Gold in London! It seems Cheryl's recent foray into Haute Couture rubbed off nicely - did you know Sarah & Nicola are BOTH wearing a designer we have seen on Cheryl? I'll give you a hint... her white floral applique dress.. BRIT Awards...

Yup, this is Georges Chakra, the Lebanese designer who shows his couture collection in Paris. Sarah wore an unbelievable black sequined gown with transparent stripes on the back - this is from the designer's Autum/Winter 2009 collection.

And not to be outdone, Nicola Roberts stayed true to her love of all things feminine in a one-shoulder white dress with organza petals, sprinkled with pearls. This is from the designer's Spring/Summer 2009 collection. The photos are gorgeous, but I suspect in person these dresses were magical! Not to forget Kimberley Walsh, who stayed true to the (seemingly) black & white theme in her strapless black cocktail dress! Photos below...
