Sandra Bullock was absolutely drop-dead gorgeous at the Oscars last night and rumor has it that the dress by Marchesa was constructed from vintage materials. Amazing.

We didn’t see any of the exceptional sustainable gowns from Gary Harvey (right), but thought if there were a place to wear such a creative manifestation of recycled fabric, the Academy Awards would be the place to do it! Maybe some of our leading ladies will catch on to that for next year…

We love the contrasting styles of these two reality TV ‘It girls’ from The Hills. LC is picture perfect classic with a tailored blazer, peep-toe shoes and a timeless white blouse. Now for the sustainable style makeover! This look is quite classic, and requires an investment in a staple blazer. Stella McCartney delivers amazing tailored pieces that have designer details with a real wearability. Build the look with a white oxford shirt from Bamford, and a softly structured skirt from EcoSkin. Finish the look with a sweet pair of vegan ‘patent leather’ peep-toe pumps from Neuaura.

Prefer the edgy look sported by Audrina? We’ve got you covered! Audrina balances a slouchy causal top with street chic jeans and standout shoes. SUST is your go-to for California chic layers. Opt for their Disco Top in a number of colors. Who better to provide you with street chic denim than G-Star Raw? And now G-Star is producing an eco-denim line souring organic and recycled denim. Top it all off with a stunning pair of statement shoes from Neuaura.

The romper has come full circle over the past two decades and is making a comeback that transcends seasons. Get in on the action now by pairing your romper with tights, boots and a bit of faux fur.

Transition in to spring and summer with flat shoes, oversized sunnies and of course a boho carry- all bag. Inspired by the romper trend? Snatch up the featured romper on the right from Claire Incorruptible- an online vintage retailer. This romper is a Ralph Lauren original from the 80s!

From the resort collection by Vera Wang, we get an easy breezy feel for the spring ahead. There is a return to the feminine influence with sweet cuts and sheer fabrics.

The eco-minded brand, Bodkin, has rolled out some amazing effortless pieces for warm weather dressing. This dress is a favorite of ours and captures a certain 1940’s feel with a modern twist. Mens shoes were huge on the runways for NYFW and you can see here how they balance the super feminine dress.

The newest ethical leather label to hit the fashion scene- Hare + Hart is a fiercely designed line that is also considered. Advocating the entire use of free range grass fed cows, and a natural acetate biodegradable fiber sourced from a sustainable forest- this line is as eco as it is chic! 

Check out an exclusive interview with Co-founders Emily Harrison and Jennie Engelhardt in a Designer Insider Interview on GretaGuide.

The leather blazer is a look that blends classic and edgy- effortlessly. Here Taylor Momsen is sporting the new leather jacket at the Mercedes-Benz Fashion Week S/S 2010.

This season, Hare + Hart is producing a fantastic leather blazer sourced from Argentina, where the cows are free-roaming grass eaters who are also used for consumption, so the whole cow is used. For anyone who is not yet ready to give up leather, but wants to engage in more ethical leather purchasing- this line is for you!

The puffy jacket is the only resource to stay warm when the temperatures drop- but it doesn’t have to mean that you lose your shape or style. In fact, this season the puffy has had a revival. Wear it cropped or sinch it in with a belt for a modern take.

This jacket from Kuyichi is a great cold weather option with chic style. Made from recycled plastic bottles.

Available at Ascension.

Loving the oversized layer trend- especially the snoods! What a funny word and an even funnier bit of fabric that actually looks super chic.

Falling right in line with this oversize concept, adding versatility and and eco edge is the line Elementum. The perfect accomplice to this oversized trend- but with some staying power.

The runways during fashion week in Paris were overflowing with ruffles galore! Aligned with the turn in the finance world- fashion is taking on a lighter more hopeful feel. It is the return of romance.

Bring this trend into your wardrobe with a ruffle detail top. The exaggerated ruffle neckline draws the eye, and is perfectly balanced with a longer length to be worn as a dress or long top. Top by Richard Nicoll, available at People Tree.
