I love all 3 but voted for tights. Support tights keep my legs healthy. They were prescribed years ago to treat a circulation problem I got from a bad car wreck.
Fave brands: Solidea for tights, Wolford and Falke for pantyhose, Torrid and Fabletics for leggings.
The Solidea tights I buy are sheer and look just like pantyhose. They have a bit of shine, are super comfortable, fit great, and feel fabulous.
