Iskra Lawrence swaps her underwear for outerwear as she proudly displays her curves at lingerie bash in NYC

She is a poster girl for body confidence. 

And Iskra Lawrence proved that more than ever when she boldly opted to display her lingerie while living it up at the Aerie Celebrates the All Woman Campaign, of which she is the face, at the Aerie Spring Street Pop Up Shop in New York last week. 

The 26-year-old Brit looked sensational in a nude body worn under jeans, with her eye-popping bust and flawless curves helping her grab the attention at the bash - making her the perfect frontwoman for the job.

Iskra is currently collaborating with American Eagle's Aerie lingerie label for their 'REAL' campaign, which aims to encourage body positivity - a cause for which she is a relentless campaigner.

As they celebrated the launch of the Aerie campaign, the Worcester-born beauty was the perfect advertisement for the brand thanks to her flawless curves. 

Rocking the body, the lacy material flashed even more flesh as her skin was directly visible underneath while she also went braless beneath the body. 

She pulled on loose-fitting jeans to dress down the look slightly, while the tattered detail on the trousers made her look super edgy. 

Iskra once again gave her own cool addition to proceedings with stone-coloured suede ankle boots, with a pointed toe.

In the spirit of the natural beauty movement, she kept her make-up totally pared back and neutral to make the most of her stunning good looks. 

Her blonde tresses were worn in beachy loose waves, permitting a surfer girl feel, while she pinned a light pink rose behind her ear for the party. 

Iskra appeared to come over shy as she later pulled on a jumper to mask her incredible curves.  

The blonde beauty's figure-flaunting display comes after she shared an unedited, natural snapshot of her stomach. The runway star could be seen modelling a lilac bralet with a diamond shaped cut-out and a pair of patterned knickers.

On the left hand side of the image, Iskra is relaxed and leaning forward, her stomach naturally rounded, while on the right she is posing and sucking it in.

The blonde beauty commented: 'Your fat rolls are beautiful. I made a video about them (link in my bio) And the reason we have been lead to believe they aren't is because we don't see them in the media unless someone's being shamed for weight gain or ridiculed for their body.

'This is NOT the truth and not OK. Having rolls of skin / fat that are soft / squidgy or big / small does not define your beauty. 

'I wanted to show you how my body looks when I'm relaxed and when I'm posing right next to each other so you can see how easy it is to manipulate how a body looks. (I filmed myself doing this for you on my YouTube.

'As a model in the industry 13years I've seen nearly all the pics chosen of me for lingerie & swimwear shoots are the ones where my stomach looks flattest. Which for a long time lead me to believe that's how I should look.

'Because even if I did happen to have a few shots where I'm in a position you can see back fat or rolls someone had decided it's more "beautiful" "aspirational" or will inspire more customers to buy the product if those so called "flaws" don't exist.'

Iskra went on to praise Aerie lingerie's 'REAL' campaign, which aims to encourage body positivity. The blonde beauty was the poster girl for the innovate Photoshop-free campaign in 2014, which helped boost sales for Aerie.

She continuted: 'Things are changing I remember the first time I saw curvier models in editorials with their rolls and back fat and I remember the first time I shot with @aerie and they wanted me to not pose but be real and just myself. Then when I saw my first campaign with them and I could see my unretouched body - pics with rolls / back fat I'm not gonna lie I was shocked.

'That quickly turned into joy because they made me feel good enough and knew that those "flaws" didn't mean I wasn't beautiful in fact showing that their models didn't have to be "flawless" was incredibly empowering.'
