Pregnant Sienna Miller divides fans with her show-stopping ‘duvet-inspired’ outfit choice at Vogue World – but what do YOU think?

She led the stars on the red carpet at Vogue World on Thursday evening.

But Sienna Miller has divided fans over her duvet-inspired outfit choice at the star-studded party.

The actress, 41, turned heads on the carpet as she pushed the boundaries of maternity style in the voluminous skirt and plunging shirt.

Fans flocked to Twitter to debate whether she stole the show or actually suffered a style blunder.

Those in favor of Sienna’s outfit choice wrote, “Now that’s a pregnancy glow.”

‘OMGOSH’

‘She looks so cute here. She’s radiant.’

“Sienna Miller took the right page out of Rhianna’s pregnancy manual.”

‘Mother with beauty’.

Meanwhile, those who weren’t so partial to the outfit thought Sienna had a huge style flaw.

Critics wrote: ‘Who were the worst-dressed stars at the Vogue World event: Sienna Miller and Kate Winslet led the way.’

‘Stolen the show? For the wrong reasons, yes. Worst dressed.’

‘Unsure’.’

Why does she fold herself up with a curtain?’

“How can anyone say Sienna Miller looks beautiful in that horrible, horrible dress?

Sienna confirmed last month during a beach holiday that she is expecting her second child with partner Oli Green, 26.

She is already mother to daughter Marlowe, ten, with her ex Tom Sturridge.

She completed her dramatic look with a pair of opaque stockings and a pair of black heels.

The star pulled her blonde hair back into a chic updo and accessorized with a pair of gold chandelier earrings.

The event – ​​dubbed Britain’s answer to the iconic Met Gala – had a legion of all-star attendees.

Vogue World acted as a fundraiser for the British performing arts industry, with the magazine’s editor-in-chief Anna Wintour overseeing the work and Vogue editor Edward Ennful also present.
