Kate Middleton lace Temperley dress at War Horse premiere was the epitome of glamour

Who wears lace with grace On Kate it was the epitome of glamour, but it's a look that can easily go horribly wrong

Stepping out in floor-length black lace can be risky – you don’t want to end up looking like a human doily.

But when the Duchess of Cambridge hit the red carpet in a demure yet dramatic Temperley gown at the film premiere of War Horse on Sunday night, she triumphed again.

The dress was a bold choice for Kate – the scalloped neckline plunged provocatively and the nude underlay gave the impression of flesh beneath.

But combined with the bracelet-length sleeves (a hot trend for spring) and full-length sweeping skirt, the flash of decolletage seemed just right for the red carpet occasion.

Kate’s gorgeous glossy hair and pared-down accessories also stopped her from looking too formal, and kept the ensemble fresh and modern.

But for every lace hit, there’s a faux-pas, as the stars featured here prove.

The secret seems to be to choose a dress in a simple cut, which doesn’t detract from your figure, and team it with minimal accessories and unfussy hair. It’s a formula the style-savvy Duchess sticks to every time – with stunning results.
