Sienna Miller is busy. In addition to clocking eight performances a week in "After Miss Julie" on Broadway, the actress is also co-designing her ready-to-wear collection Twenty8Twelve with her sister Savannah who lives in London. But the girls are not letting the Atlantic Ocean get between them.

"That's the wonders of modern technology. We Skype a lot," Sienna says. "There are such great vintage stores and fabric places here that I can source and send my ideas back to Savs and vice-versa."

On Monday--Sienna's only night off--the Miller sisters spoke with WWD about what's next for the British label.

WWD: Sienna, you just moved to New York temporarily and Savannah, you're visiting here for the week. How are you finding the city so far?
Sienna Miller: I love New York. I was born here so I feel like I have an affinity with the place. But I'm here just for four months doing the play.
Savannah Miller: I love the pace here. London's great but it's a sleepy town compared to New York. This is on a completely different level. The energy is so exciting and it's impossible not to get caught up in that.

Typically, costume designers get into the trade hoping it will take them one step closer towards their ready-to-wear design aspirations.

But Peter Speliopoulos, Donna Karan's creative director, is taking the opposite approach. Speliopoulos, who has also designed for Christian Dior, Carolyne Roehm and Cerruti, created the costumes for Itutu, choreographer Karole Armitage's latest production. Itutu premiered Friday at the dance company's Armitage Gone! annual gala held at the Brooklyn Academy of Music.

New Yorkers will never look out their windows the same way again.

In his latest work, "City Out My Window: 63 Views on New York," illustrator Matteo Pericoli has recreated the city landscape as seen from the offices and homes of renowned urban dwellers including Mikhail Baryshnikov, Mario Batali and Philip Glass.

Two months ago, while all of Manhattan was in a frenzy over Fashion's Night Out, two artists at Intermix engaged in an art battle. While shoppers watched, the painters smothered mannequins in neon yellow, sky blue and gold lacquer. While it helped stir up excitement for the night itself, the demonstration was also being taped for the Web series "RADAR: Art Battles," which starts its second season today.

Kia Pedersen wants museumgoers to get a feel for her artwork -- literally. Hence the name of her latest solo exhibit, "Please Touch." "Everyone walks in and the first thing they say is, 'Can we really?'" Pedersen said on Thursday night at her opening at KPF Gallery in New York City.

Her guests took instruction well, getting their hands on etched copper plates, intaglio-style prints and textured canvases, which were puckered by multiple gesso applications.

Fashion isn't Italy's only game right now. The country's also all about the culinary arts, but, as it has gone with fashion, the global economic downturn has hit Italy's agriculture industry hard.

One company is fighting back, one tree at a time. Nudo's "Adopt an Olive Tree" program is exactly as it sounds. For $150 a year, foodies Adopt an Olive Tree in the Le Marche region, follow its progress for a year and then reap its benefits: four 500-ml. tin of extra virgin olive oil pressed from their tree in the spring and three 250-ml. tins of flavored extra virgin olive oil (i.e. lemon, chili and mandarin) the following fall.
