With rumors swirling that Sienna Miller will eventually marry on-again / off-again boyfriend Jude Law, the question has arisen as to whether her sister Savannah Miller might design the wedding dress. Savannah says probably not, as top ten fashion designers like John Galliano will likely be trying for the job.

Savannah and Sienna Miller collaborate in the fashion industry on a clothing collection called Twenty8Twelve. Sienna has been engaged to Law before, but broke things off in 2006 after he had an affair with his children’s nanny. But by the autumn of 2009 the two were back together again, and marriage rumors have resurfaced, with Sienna saying earlier this year at London Fashion Week, “It’s going really well. I’m so happy actually, he’s great.”
