Miranda Kerr gives a masterclass in off-duty style

Meanwhile it's been announced that the Victoria's Secret model is to be the global ambassador for Earth Hour 2012

Miranda Kerr gave us all a masterclass in off-duty style as she hit the streets of New York yesterday with her adorable pooch, Frankie.

The model, who we saw walking the runway during the Chanel A/W'12 show at Paris Fashion Week, looked as if she was ready for a fashion shoot in a vibrant checked jacket, skinny jeans and a statement bag.

Sleek tresses and some on-trend sunglasses completed her NYC spring time look, while little Frankie only added to Kerr's glam power.

It's just been announced that the 28-year-old Aussie model has signed up to be the global ambassador for Earth Hour 2012, which encourages the public to switch off their lights for 60 minutes on March 31 to conserve energy and encourage sustainability.

The Victoria's Secret model, who's married to Orlando Bloom, has promised to hold a free yoga class if 500 people upload videos onto YouTube stating how they plan to help save the planet.

About the campaign, she said: 'I hope my first challenge inspires my friends, family and fans to make their own promise for the environment.

'This year I've made the commitment to reduce my footprint by offsetting all of my travel. If we all adopt simple practices like recycling, switching to energy efficient lighting or paperless banking then we can make a difference together.'

Good work, Miranda!
