This week’s Best Dressed is a special one; both the dress and its wearer look amazing on the catwalk.

It’s always a breathtaking sight when we spot a model in a stunning gown, and what better designer to turn to than the maestro of red-carpet style, Zac Posen.

Supermodel Coco Rocha wore the stunning tulle edelweiss embroidered gown from the Zac Posen Spring 2012 collection, and boy oh boy did she look like a dream in it!

Hardly in need of any accessorising, the gown has beautifully crafted butterfly wings situated atop the shoulders which Coco showed off by wearing her hair in a wispy up do. Form-fitting with a dramatically embroidered extended trail; just like the lady,Coco’s look is flawless.

With a barely there berry stain on her lips to ensure the pale green gown didn’t completely wash her out, Coco opted to go sans accessories and it worked. An all-eyes-on-me gown like this surely needs no enhancement in any way.

A no brainer for this week’s BDOTW!
