The model, 23, who worked with the brand on their spring campaign this year, wore a pink blouse with a ruffled midi skirt.

Arriving at Southbank’s National Theatre, she layered a matching shirt over her top and added a pair of quirky shoes, that zipped up the front.

Iris slicked her platinum blonde hair down and accessorised with a black headband and gold hoop earrings to complete her look.

The best of British heritage welcomed the best of British talent as Burberry presented its latest collection.

The enduringly popular fashion house debuted the forthcoming range in front of a celebrity-packed front row at Southbank’s National Theatre.

Luxury fashion giant Burberry – a London fashion Week veteran – is one of the handful of brands publishing scientific targets with its materials and production techniques.

Known for its tartan branding, the fashion house recently raised its emission reduction goals and hopes to be carbon neutral by 2040.

But BFC chief executive Caroline Rush said: ‘To set carbon reduction targets, you need a team to be able to measure your targets, understand how to reduce them and then report on them.

‘For a small business that’s quite a challenge.’

To help, the BFC now has some 50 businesses that will go through its “low carbon transition” programme for designers.

Ideally, advocates say the programme should be extended to help brands monitor and report their carbon reduction plans.
