Last week Sienna and Savannah Miller announced that their Twenty8Twelve collection will make a debut during London Fashion Week on February 22. But their small business is as Capricorn as it gets. The venture was named after Sienna’s birthday (December 28, 1981) but her older sister wasn’t born that far away. “Mine is just few days later,” explained Savannah. “But she’s younger, so she gets away with many more things. But obviously we’re both Capricorn which makes us very alike.”
