There are well-cut coats with pleated skirts, lovely blouses done in collaboration with artist David Cooper who designed the print, and fantastic jeans with zips up the back that were the idea of Sienna. I'll have pictures soon, so stay posted.

Best of all, the pricing is really reasonable. The most expensive coats are only 345 pounds (or about $650) and the shirts begin at 40 pounds (or $80).
