Oh where to start on my favorite pair of leggings ever.
I literally live in my Stella leggings the second it gets below 60 degrees. I bought my first pair over a year ago and they have somehow gotten more comfortable over time. They are durable, not see-thru, and fit incredibly well. I try to wear natural fibers whenever possible because I overheat in synthetics and I spent a loooong time looking for a good pair of natural fiber leggings. The Stellas are it! WoolX has improved the fabric and fit over the past year, as I just purchased two new pairs and they are somehow softer and smoother than my first pair. They also tightened up the ankle opening, which was wider than I liked initially.
I bought a Large and am 5'11, ~190 lbs with a 34" inseam. The regular length hits perfectly above the ankle. I also own the longs and those go below my ankle. It all depends on how you want them to fit. You really can't go wrong with these leggings and may end up owning 6 pairs like me :)
