Sheerly amazing! Olivia Palermo goes braless in see-through blouse from her own collection during NY stroll

Olivia Palermo debuted her new designs for the Chelsea28 Fall Collection during New York Fashion Week.

That made the 30-year-old fashionista was the perfect person to showcase her own creations during a walk through New York City on Wednesday.

Olivia took it a sexy step further by flaunting a sheer black blouse that she'd hand in designing and no brassiere underneath.

She breezed along carrying a shopping bag from Foragers market and restaurant and sipped a freshly blended smoothie.

If Olivia looked relaxed it's because she recently got back from Greece where she and her husband Johannes Huebl enjoyed a few days to themselves.

The couple's holiday included a dinner out in Mykonos with designer Valentino.

Perhaps Olivia was bouncing off design ideas to the royal one of designing houses.

Speaking to Vogue about her collaboration with Nordstrom's Chelsea28 label, the native New Yorker said: 'It’s important to understand what a girl wants. And Nordstrom has a similar take on the New York woman - she’s a woman on a mission who knows what she’s looking for.'

She added a pair of clean white loafers with black bows on top that, along with the ruffles on her blouse, gave her look an ambivalent twist.

That is part of the fashion blogger's signature style, which mix high-end and low-end fashion.

On Thursday, Olivia took more care to cover up, wearing a pair of shiny black leggings, black top and a army-green jacket along with cobalt-blue trainers.
