Oiselle Black Capri Workout Leggings Small

Oiselle capri workout running yoga leggings in black with light gray seams. The sides just under the waist band have small triangle shaped mesh vents.. The seams on the rear are very figure flattering. Inseam is approx. 14". These have a loose thread on the knee detail - see last pic. I imagine this won't move much but would also be an easy fix. Size small, good condition.
