Best opaque tights
I've tried about a million varieties of opaque tights, and these are by FAR the best. They are like a black hole of opaqueness; no light escapes. Highly recommended if you want opaque tights that are honest-to-god opaque with not even a tiny bit of flesh tone showing through.
They're also very soft and comfortable, with better stretch than leggings. Not that that matters, though, since these tights are even more opaque than leggings.
Wicked highly recommended.
