Dannii Minogue was a perfect vision of loveliness on Saturday night when she stepped on the X Factor stage.

She wore a nude Philip Armstrong Spring 2010 metallic dress which had a bow neckline.

This is the type of structured interesting non-predictable dress I want to see more of from Dannii.

The mother of one looked sophisticated and effortlessly elegant.

This is the second time since the show started that I really loved – instead of just liked – her look.

Stephen Webster and Annoushka jewels, plus Brian Atwood nude heels completed her look.

She was easily my favourite this week.
