Tights can be very delicate and easy to ruin with a single snag. If you dampen them with water, then freeze before wearing them for the first time, they will last longer.

Leeann Duggan at Refinery29 explains:
When you buy a new pair of tights, run them under water for a few seconds, squeeze out the excess, then freeze them overnight in a plastic bag.
When you take them out of the freezer, let them come to room temp gradually before wearing. You only have to do this prior to the first wear, and it's said to extend the life of your tights.
Tights can be a wardrobe staple in any season, so making them last longer will save you both money and frustration. For more tips on how to stop ruining your tights, check out the full post linked below.
