A yay from me
If worn properly. I have some black ones - they're just like skinny jeans really but a far more comfortable. Bit more hard wearing than leggings - don't get them mothy holes along the seams after a few washes
As a rule of thumb, the older / fatter you are, the longer yr top or dress should be you wear with them. Yins out the yang mutton
With good boots / snazzy heels they can be v flattering to legs
