ABC News' Taylor Behrendt and Tara Berardi report:

The Golden Globes red carpet was packed with some major fashion show-stoppers, but two unique looks in particular had heads turning and people talking.

The first was Harry Potter starlet Emma Watson, stunning the crowd in a peek-a-boo pant number by Christian Dior.

Cameron Silver, owner of Decades in Los Angeles, notes that Watson has rocked the pants look before and says we should expect to see it even more in the future.

"What I loved about Emma Watson's look is that she looked demure from the front, but gave us complete drama in the back," Silver told ABC News, adding this style could be a hint of what might be seen next week in Paris at the couture shows. "I think this is a very modern, fresh perspective on how to dress. This was definitely the intention of the look."

The other hybrid that had tongues wagging was Julia Roberts' Dolce and Gabbana number, which was designed just for her. The belted and bejeweled part dress and part blouse ensemble caused a frenzy online.

"This year she gave us a new idea and I think a lot of people were surprised," said Silver. "But she's a trendsetter in her own non-fashionista way. She's never a fashion victim. She wears what she likes and Dolce and Gabbana custom-made this look for her and I thought it was really flattering."

Roberts told Ryan Seacrest she tried on four or five dresses before making her choice.

"This just seemed like, 'That's what I am looking for,'" the actress said on E!

There was speculation that Roberts got the dress and then decided to add the white blouse, but Silver says Dolce and Gabbana created the whole look.
