Thanks for your brilliant suggestion about the seats in my skirts.
I had a look at them,
one has a back seat in the center of the skirt,
the other two side seams.
I phoned a female friend who knows of my chosen lifestyle
She came over and has already opened the back seam for about 9 inches
This has solved the problem completely and with a bonus which I will explain.
Katherine has made good the seam very neatly and the bonus is that when I wore the skirt with a slip under each,
which I nearly always do,
it gives a tantalizing glimpse of petticoat when the slip opens as I walk.
I like that very much.
