Quality tights, including our top picks here, are not see through. But tights on the market that are not made with thick enough or high-quality material can be transparent.
You can check to see if a tight is see through by doing a squat test. Try the tights on in front of a mirror and squat down or touch your toes. Look back in the mirror and see if you can see any skin or underwear. If you don’t see anything, you are good to go!
