I remember leggings from first time round- 20+ years back- when I wore flowery Laura Ashley ones. Gawd.
I do have a pair that I wear with an almost-dress- but lots of pics of autumn wear have them teamed with quite short tunics.
I am old ( though look mid 40s I am told) and a size 10.
Another problem is that you have to have a full length coat when it's cold, otherwise you look as if you are wearing a mini skirt and tights with a 3/4 length coat or jacket.
