As a former Victoria's Secret Angel supermodel Helena Christensen is an expert in lingerie. And it shows.

At the after-party for Calvin Klein on Thursday the 41-year-old stole the show in a low-cut strapless dress.

And it was all thanks to her judicious use of a pu$h-up bra.

Stealing the show: Helena Christensen wore an eye-catching strapless dress to the Calvin Klein after party yesterday

The underwear turned the beige basque dress into an eye-catching outfit, which Helena emphasised with a gold necklace.

Earlier in the day, at the designer's Autumn show, the mother-of-one had looked completely different.

In place of the show stealing cleavage she would later display, she wore a modest bronze crinkled dress.

What a difference: Earlier in the day Helena looked demure at the Calvin Klein Autumn fashion show, then she slipped on her push-up bra

Fans of the photographer should feel no surprise at her revealing choice of outfit.

'I have no problems with showing my body,' she revealed in a recent interview.

‘I’m Danish. Everyone’s naked on the beaches.

'We don’t really give a s***.’

A lot of front: Helena says she does not mind showing 0ff her body
