I've only had one pairs of leggings and I didn't like them, my daughter used to wear them but now wears plain leggings, which are practical for her work.
I had 2 or 3 pairs of cheap leggings which I wore sometimes but found that they got baggy quickly and the top of the thighs wore through quickly. All that sort of leggings has been ditched apart from one pair that keeps surviving the chip as they are useful for doing dirty work outside. I was recommended mint velvet leggings and they are good quality and comfy.When I broke my arm I needed easy to put on clothes, the baggy tops that went over my cast went but I have kept the leggings I have some plain black, grey and burgundy ones. Often wear the black and burgundy ones in winter under dresses with boots instead of tights. In the last couple of years I've got myself some sale ones from llama leisure, as I wanted some jolly coloured patterned ones, and have several lovely pairs, psychedelic, and 60s flowers, as well as more subtle ones. I need both plain and patterned ones, today I have a black pair plus a psychodelically patterned early 70s style top, just the job for church. I make sure that tops are tunic length, maybe not if I'm home alone, but for going out. I do wear skirts more in summer particularly and dresses.
The colours/patterns cheer me up and I have had some people come up and say how much they love seeing the lovely colours
If you enjoy wearing leggings/leggings, just go ahead and wear them, if you're worried about how you look just have a peek in a long mirror and if you're happy with what you see why change it
Actually, looking at myself in a long mirror has helped me declutter my wardrobe, some things that I thought suited me style/cut wise, in fact,didn't.
