They’ve been crafty awesome outfit for Twenty8Twelve for six years, but now Sienna and Savannah Miller are packing their equipment and moving on.

The Miller sisters told press, “We’ve had a brilliant six years at Twenty8Twelve and are now looking forward to new pastures. We wish the brand the best of luck for the possibility.”

And it sounds like Nish Soneji, the managing director of Twenty8Twelve, is sad to see Sienna and Savannah go.

“We’ve had a fantastic partnership with the Miller sisters. That vision, along with the uniquely British style the collection has become known for, will continue under the direction of the Twenty8Twelve design team.”
