In tune with the retro trend in sunglasses - the white frame especially is making a powerful comeback this year - an exaggerated, 1950s-inspired cat eye shape is surfacing on trend site

Alexander Wang's first range of shades set the trend and now other brands, such as Ray Ban, Opening Ceremony, and Fossil, are following suit, an interesting trend given that the shape is also becoming popular in makeup again, with many labels opting for exaggerated cat eyeliner looks at recent fashion shows.

In brands, shoe guru Christian Louboutin has climbed his way back to the top, but the new generation - Gianmarco Lorenzi, Charlotte Olympia -are on his heels.

Finally, Earth Day on April 22 caused the Polyvore community to shop on the eco-conscious yet stylish site,, and Gossip Girls Leighton Meester, Taylor Momsen, and Blake Lively are upping their fashion cred.
