Thanks for the ideas and suggestions, peeps. I looked at the posh leggings and gasped at the prices of some. Also, I don't like polyester. I try to stick with natural fibres.
I've tried more close-fitting leggings under fairly close-fitting trousers. Unfortunately I find that too painful. Close-fitting is OK but it has to be very soft and flexible not to cause (or increase) pain.
I had found the House of Bruar cord skirt and liked it. Just the fussy tabs at the waist put me off and the price a little bit, though I'd pay that if I was going to wear the garment a lot (thinks: 'wear it to death').
I'm not keen on the fit and flare style.
I might make one, anno – could easily and have done in the past, but there is no decent fabric shop anywhere near, which is a bit limiting.
I think I'll take another look at Orvis, except theirs tend to be too long for me.
Difficult? Fussy? Me?
