Boden, Seasalt and Banana Republic are usually good for me, but I can't quite see anything that is right. I want a couple of maxi dresses that go right down to the instep, not ones that cut off at ankle length, but I'm a bit tall (5'8) so this is hard to find. Simple flowing shape with a high-ish waistline would be nice. I'm fairly slim and 40 ish. Any ideas? My current long maxi dresses are worn to death and now have holes in them, really need some replacements before the weather gets much hotter!
