Faux leather leggings have been a fashion trend for several years (seriously I was discussing the style merits 0f faux leather leggings back in 2016) and they don't seem to be going away any time soon.
FAUX LEATHER LEGGINGS
Keeping it real, this is the most popular way that I and most women I know wear their faux leather leggings. They're easy and comfy but elevate weekend basics so you don't look as though you're running around town in your pajamas.
The way to make faux leather leggings look great is to treat them as though they aren't leather; style them as you would a pair of skinny pants or ponte leggings and you'll have the best results and not look like you're wearing a costume.
