Sarah HardingSarah HardingThe Girls Aloud gals have come a long way...

Especially where their style is concerned.

When the band first emerged on the scene, we saw a more down-to-earth, girly group of chicks.

They've certainly revved up the sex factor since, sporting more flashier, colourful outfits...

Sometimes even leaving very little to the imagination.

Example - the girl's body-hugging mini dresses for a recent fashion shoot for Sunsilk hair products.

OK, so this colourful look probably won't go down in the books as a fashion hit...
