Sienna Miller has teamed up with her older sister Savannah to create a fashion line of women’s clothing which they call Twenty8Twelve and premiered their first ever runway fashion show to debut their Fall/Winter ’09/’10 Collection at London Fashion Week in front of a packed house of celebs and fashionistas this week. Here are a couple pics of the Miller sisters as they took their turn down the runway at the completion of their show and some info on show and collection:

Last night, the actress Sienna Miller should have been on the red carpet at the Oscars in Hollywood. Instead she was on her knees, on the floor of an old diary in West London, putting the finishing touches to a fashion collection. This was not her latest film role, but a real-life scenario as co-designer, with her older sister Savannah, of the Twenty8Twelve fashion brand. The latest collection, for autumn/winter 09/10, made its catwalk debut at London Fashion Week last night before a packed audience of press, buyers and celebrities, including Courtney Love, Alexa Chung, Kanye West, Francesca Versace, Daphne Guinness, Mary McCartney, Jade Jagger, and Twiggy. The clothes appear, on the surface, a reflection of the two sisters: punk, boho and biker-influenced leather jackets and skin-tight, body-conscious dresses in peek-a-boo stretch for Sienna’s hectic trans-Atlantic, movie-star lifestyle; crystal-embellished cashmere knits, finely-tailored “highwayman coats” and floral-print tunics, perhaps more suited to Savannah’s life as a wife and mother to two children in an eco-friendly, “The Good Life” setting in Gloucestershire. “But put them together and it says London cool,” said Sienna, backstage before the show. “These clothes are funky, and there’s something for anyone.” Must-have items included soft, high-waisted, denim leggings, backless tunics with Swarovski crystal-shoulder-pads – “like an American footballer”, said Sienna – a Charlie Chaplinesque trouser suit in grunge-tweed and a long, black and white, jacquard-knit cardigan-coat in what Savannah called “London camouflage”. The two Miller sisters launched the collection – named for Sienna’s birthday – two years ago. “Sales have been very good, particularly in England and America, and we felt it was the right time to do a show,” Sienna said. “I’m not giving up acting, I love acting. But I also love working with my sister. We’ve always been two sisters playing dress-up, ever since we were kids and we’re still doing it.”

The bad news appears to be this quote from Sienna, “I’m not giving up acting”, but the good news is that Sienna has now got a new endeavor to keep her bizzy and out of the company of other women’s husbands … not that this new venture is gonna stop her from that practice. It’s interesting that with all those celebs packed in the front row of Twenty8Twelve‘s first fashion show, Sienna‘s married paramour Balthazar Getty was nowhere to be seen. HMMM. After the jump, check out a few photos of some of the Miller sisters’ designs making their way down the runway to judge the threads for yourselves …

My advice would be to put down the Bedazzler and tone down the sequins. I don’t, personally, see anything that is all that thrilling … some of these outfits look like they could be sold at Dots. My guess is that the collection will prolly sell marginally well because of the celeb designer connection but, as we’ve learned from Victoria Beckham‘s failures as a overpriced denim designer … name recognition doesn’t always equal sales in the long run. What do y’all think … would YOU rock anything from the Twenty8Twelve line?
