I'm looking for a pair of tights that are the thickness, weight and opacity of a pair of black microfibre leggings I already have. Actually, the leggings are technically long underwear--ha!--but they work beautifully as leggings. They're completely opaque--no skin shines through on the thighs, for example. I want to wear then during the holidays with some shorter sweater dresses I have. We don't wear shoes inside here in Canada, so I can't really just do leggings with socks and boots over. That's why I want tights. I don't want wool.

Has anyone come across anything like this?
