It eliminates potential chafing between the legs and can be worn with all casual flat sandals. Tunics - you could try White Stuff, Fat Face and Mantaray. Saw this in Top Shop if you don't mind exposing arms, or wear a navy short sleeve body under it, or a thin ballet cardi over for evenings. http://m.topshop.com/h5/product?productId=23932166 TKMaxx have adventure sandals (no toe posts) which are brilliant for hot hols. Can't remember the name, but something + Earth' is one of the brands with good support.
DianaT I really like that top! I've had a look at the White Stuff site and I really like some of their things I wouldn't have thought of looking there! And I think I might even wear them again when I'm home!
Also had a look at TKmax and ordered a couple of tops.
curtains I really like the white sandals, I'm awkward with footwear thanks to an arthritic hip but they might be fine for an evening meal! not too much walking.
I'll also have alook at sketchers, I've heard other people recommend them as well.
Thanks everyone, at least now I've got an idea of where to start
