Personally speaking, what I’ve seen of the Twenty8Twelve range by Sienna and Savannah Miller hasn’t exactly set my world on fire, but there are a few serviceable pieces in there. If you’re itching to get your hands on clothes designed by Sienna, though, it’s now available in the UK through ASOS.com, where this cropped tuxedo jacket is £220 and the "only for people with great legs" wool mini skirt is £100.

It’s expensive, but is it worth it?
