Bluesuits makes great shift dresses in all year round tropical wools or cotton. They take you from day into evening. Great for work with one of their matching jackets. You can choose from sleeveless, cap sleeve or 3/4 sleeve.
oooh this is a thread I have been meaning to start! will be watching with interest...
Shift dresses are my favourite for work
I hunted everywhere, but didn't have much luck this year.
did find a couple of linen ones in Hobbs this year (not normally somewhere I find clothes that I like). The ones I found in M&S really weren't flattering and I didn't think they were very well made, although they were fairly cheap.
