MILLER TIME: Sisters Sienna and Savannah Miller made a quick trip to New York on Thursday evening to mark the launch of their spring-summer Twenty8Twelve by S. Miller collection at the rooftop of the Gramercy Park hotel. "I need a vacation," said Sienna, who left on Friday for Los Angeles to continue working on a new film. "I wish I could just come to New York for a break, but that hasn't happened in such a long time."

She did, however, manage to dodge the paparazzi for a little while on Thursday morning when the girls went out for some quality sister time. "We had a really great sister moment today and went to a little place down the street to get our nails done," Sienna said.

As for the collection, don't expect to see it on a runway soon, although the sisters said they hope to show one day. "For me, there has to be a real reason to have a show," said Savannah, who used to design for Alexander McQueen. "At McQueen, the clothes called for a production and he really puts on a real show." Sienna agreed, but said, "I would love to have a show someday, maybe if we are bought by the Gucci Group. Then we can have one."
