March is host to Earth Hour, a measly hour dedicated to raising awareness with the hope of increasing environmental care. For some, Earth Hour has less of an impact on their routines, because as they maintain a lifestyle that incorporates environmental friendliness every day. Stella McCartney is one of those people.

A vegan and longtime advocate of “meatless Mondays,” McCartney is known for encouraging omnivores to go veggie at least once a week as cutting meat out makes a huge and positive environmental impact. McCartney, daughter of Sir Paul McCartney, is better known for her environmentally friendly designs than her food choices. With a reported 34 per cent increase in revenue this season, she's clearly making a positive payoff for the environment that's a lot more glamorous than sitting in the dark for an hour.

McCartney's spring/summer 2012 collection is nothing short of divine. Bloggers, fashion editors and women everywhere love the simplicity and elegance of the garments and their wearability. Little white dresses done in mesh with bold stretches of black, green or blue were simple counterparts to the dresses in mixed prints, all detailed with corded embroidered swirls. A few pops of red in the form of slacks and a knit patterned sweater complemented the muted soft grays in the collection. Sheer tops, trousers, matching top and jacket sets, skirts and McCartney's staple, jumpsuits, were all done in modern, graphic prints. Floaty, easy, silk pajama sets in paisley and sheer gray gave a nod to the sleepwear trend.

Nude, minimalist heels paired perfectly with the collection and were met with equally neutral nails. A simple, slicked-back, twisted bun showed off McCartney's famous no-makeup makeup look that legendary makeup artist Pat McGrath has been creating for McCartney's models for many seasons past. Medium-sized cylinder shaped duffel bags lent a sporty vibe while a small, white faux-leather clutch with a chain handle worked beautifully with the evening pieces.

The light-as-air collection “is a celebration of energy, freshness, and fitness,” said the designer. Still creating collections in collaboration with Adidas, McCartney is no stranger to designing fitnessinspired wear. This season, coral, frilly bikinis and black cut-out swimsuits were met with the always bright and punchy separates. If wearing these modern, dreamy pieces helps the environment, count me in.
