I'm in a cold climate, I like wearing dresses at work and I wear pantyhose all the time. Never nude or suntan hose though, mostly opaque and colours I like. I have opaque matte purple, medium dark blue with vague striping, black of course, I had a pair of favourite dark red ones, but I got so many red-stocking comments that I gave up on wearing them. Besides they went baggy on me. I also have some very cool black and white swirly ones, and some green shimmery ones, but they just look too weird once I put them on.

Or is this what you call patterned tights? They're thin nylon and with feet. For dressy occasions I wear black stay-ups to avoid the dreaded waistband digging in, not opaque.
Oh, and I'm 43.
