Oscars 2015 fashion will be anything but boring

There will be no shortage of hot looks and glamour at the Oscars red carpet come Sunday.

In a lot of cases, the ladies and their stylists have been plotting their gown for months.

Typically, designers will send sketches to both the stylists and the actresses at the end of the previous year.

"These sketches arrive in beautiful boxes with ribbons on them and bows. And then they send them back. It can take a good couple of months," said Zanna Roberts Rassi, senior fashion editor at Marie Claire and E! contributor.

In other cases, it's more of a last-minute decision; stylists are grabbing gowns from the runways of New York Fashion Week, which just wrapped this week.

And then there are the stars who change their minds last minute. Remember Anne Hathaway's last-minute Valentino-to-Prada swap at the 2013 Oscars?

Regardless of how or when they choose, actresses are gearing up for one of the biggest fashion events of the year. Red carpet watchers can expect a wide variety at this year's Academy Awards.

"They're anything but boring," said Rassi. "We're so used to seeing fishtail gowns -- strapless. There's no excuse to wear a boring dress anymore because there's so many amazing designs out there...What we've seen on the red carpet this season are different textures and mixed materials. It might be sequins with chiffon...like fairy tale jewels...almost like a shipwrecked feeling. They're just different."

Don't be surprised to see an Oscar attendee rocking the fringe look. "It's a big trend on the runway," said Rassi, who also works as a celebrity stylist.

"There's a movement towards fresh, clean bright colors -- so lots of white. There's always a lot of silver with the embellishments and metallics," she said.

Keep an eye out for modern silhouettes.

"There's a move towards cleaner lines and fresher-looking dresses rather than the old-world ball gowns," said Rassi.

Rassi, who recently partnered with Crest 3D White, said she's most looking forward to seeing "fresh faces" come Sunday. Like nominee Emma Stone.

"She always nails it on the red carpet," said Rassi. "She never looks like she's trying too hard. It always fits her personality."

It's true: Stone stunned in a pants suit this year at the Globes.

Rassi is also looking forward to seeing another nominee: Felicity Jones.

"She's a relative newcomer on the red carpet. She's seen in some of the biggest labels in fashion," she said.

Also keep an eye out for "Gone Girl" star Rosamund Pike.

"She's influential when it comes to fashion," she said.

The Oscars air live on Sunday starting at 7 p.m. ET on ABC.
