As a plus-size model, Crystal Renn had found a way to beat the fate of too-thin models, but these days she appears to have joined them.

Renn showed off a considerably slimmer frame at an event in New York City Tuesday night. With short platinum blond  locks and eyebrows dyed to match, Renn was nearly unrecognizable from the curvy brunette who once took the runway by storm as a size 14.

Renn maintains that she is now at a healthy medium, neither stick-thin nor plus-size.

"I've been a double-zero, children's clothes, at 95 pounds, and I've been all the way up to a size 16 and everything in between," Renn told "ET" in February. "Now I'm a 6, 8, sometimes a 10, depending on what designer I'm wearing. And that's an interesting place to be in fashion, where extremes are the norm."

Since last year, the model has been fielding criticism about her shrinking frame.

"I feel pressure - probably more from any place - probably from the public and the media," she said in an interview posted on the blog of her modeling agency, Ford. "I think that by placing a title on my head, which is 'plus-size,' and then the picture that these people have created in their mind about what plus-size actually is, I've basically failed you just with that. Because I couldn't possibly live up to that, and at this point in my life, I would have to actually have another eating disorder to live up to that expectation."

The 5-foot 9-inch Renn once weighed 95 pounds. At the age of 16, Renn, now 25, moved to New York City from her hometown in Mississippi, signed a $250,000 modeling contract, spent up to eight hours a day at the gym and starved herself.

It was clearly painful. Told she still wasn't thin enough to be a "traditional" model, she stopped struggling after she turned 18, started eating  and began a second act in the plus-size sector. She fluctuated between a size 10 and a size 14. Renn chronicled her struggle with anorexia in her 2009 book "Hungry," a memoir that made her the face of the push against too-thin models.

 Her agent, Gary Dakin, told ABCNews.com that Renn "is in between the two" sides of the modeling industry - plus-size and otherwise.

"She reintroduced exercise back into her life after finally feeling she was ready to," Dakin wrote in an email. "Hiking and yoga are part of her life now. She is healthy and feels amazing right now."
