Kristen Stewart & Ashley Greene wow at Breaking Dawn premiere

It seems like it was only yesterday when Kristen Stewart, Nikki Reed and Ashley Greene came on our style radars, thanks to a little movie called Twilight. The pretty ladies have grown up before our very eyes – and they showed off their sexy style at the Monday night premiere of The Twilight Saga: Breaking Dawn – Part 1.

It seems like all anyone can talk about is what Bella Swan's wedding dress will look like in the film. However, Stewart's dangerous J. Mendel dress caused a stir all it's own when she walked the black carpet with boyfriend Robert Pattinson.

She also donned black heels for the carpet, but later ditched them for her signature sneakers. "[My feet] hurt so bad," Kristen told Access Hollywood. "Usually they hurt. I just hurt my foot on Snow White of course, because I do that to myself all the time. So, I think this is the last interview I'm going to stay in these heels."

Of course, people asked about the wedding dress, especially since designer Carolina Herrera was with her at the premiere.

"I worked on that dress for like six months going back and forth," Herrera told E! News. "I still have all the sketches and everything because it was so special."

How did the iconic designer get her inspiration? "It was a combination of things," she said. "I got inspiration from the book and descriptions from Stephenie Meyer. You had to really take in consideration the whole story—which was this innocent girl with the first true love of her life. It had to be magical."

Ashley Greene

Ashley Greene in Donna Karan

Ashley Greene wowed everyone in a stunning red dress from – who else? – Donna Karan.

"Grateful 2 our incredible fans for all the love at the breaking dawn premiere last nite and to Donna Karan for my gorgeous dress!" Greene tweeted Tuesday morning.

Makeup artist Vanessa Scali gave all the details behind her look to RadarOnline.

"Ashley was wearing a very sophisticated dress from Donna Karan," Scali said. "The statement was the fun, bold lip so I kept the rest simple. Not too much on the eye, a soft flushed cheek and a bright, bold slash of color on the lip."

"Ashley has beautiful skin, so we kept it clean and dewy," Scali added. "For a natural glow, I used mark Good Glowing Custom Pick Powder Blush in After Glo on the apples of Ashley's cheeks and blended outward. Then, I used a touch of mark Glowdacious Illuminating Powder on the peak of her cheekbones and on her brow bones to create a warm flush."

Nikki Reed in MarchesaNikki Reed

Newlywed Nikki Reed still has that just-married glow about her – and it made her Grecian-inspired Marchesa dress look at the more incredible.

How did she choose the dress? "My decision to wear this dress is so simple and it's because it's green and it's my mom's favorite color," Reed told SheKnows on the black carpet.

Reed was more worried about how her husband would react to the film.

"I think the cool thing about this film is [Paul's] never seen a Twilight movie before and going to see this, he didn't feel like he was out of the loop or didn't understand what was going on," she added. "He was fully invested in it, even knowing nothing about the other ones."
