“Meat Free Monday” is the McCartney family’s new initiative to encourage meat-eaters to forgo meat for one day each week. I did my bit yesterday as I only had sushi.

Stella McCartney’s muse Kate Bosworth showed her support for the campaign, and for Stella McCartney’s Resort 2010 collection.

The actress wore a stunning cute ivory skirt suit.

The skirt is high waisted with a cute bow detailing, and she opted to wear her look with a white tank instead of the black runway shirt, which is perfect for a sunny day in London.

Her look was complete with Stella McCartney platform pumps.

I really love Stella McCartney’s casual style as much as her glamorous style.

Casual was the order of the day as she wore a striped blazer, a white tank, and jeans. It’s a simple everyday look, but with does of McCartney magic.

Model Anouck Lepere was also on hand for support.

She wore a grey sequined tunic dress, with low slung tie and gold pumps.

It’s like a fabulous well-dress family picnic.

I don’t think I will ever tire of this Stella McCartney Resort 2010 collection.
