Thanks for the ideas and commiseration, ladies. Today I am wearing a skirt that comes to just below my knee, and I put a large skin-colored bandage over the one larger scrape. Bruises still showing but they are light enough that I don't feel too self-conscious! Actually, I have a dark one on my elbow that I'm ignoring as well, which is probably more noticeable that my legs!
ETA, tights are no problem, it's just that I was looking forward to wearing my skirts that don't work with tights. E.g. my skirt today is stretchy and fitted and would ride up if I wore tights under it. Another skirt I can't wait to wear is midi length and celery green colored; I want to wear it with a light grey top, so black hose would just look very odd. I'm not really into wearing hose that isn't black...
