Had to order these leggings twice but they fit perfectly now and are definitely worth it.The first pair were way too loose at the top (there was about an inch gap between the top elastic band and my back when standing) so I ordered a second pair to see if I had just received a defective pair at first and the second pair were perfect!I'm 5'8" and currently 165 lbs at about 6 months pregnant and the large fits great!They have good compression in the legs and plenty of stretch in the belly. They do run a tad bit long in the legs but nothing too bothersome. They are a good material for excercising and in my experience not see through at all. Those are the two qualities I've had the biggest issues with in finding maternity active leggings. All the other brands I've tried are either too cottony feeling (comfortable but not ideal for excercise) or way to sheer.I had lost all hope of finding a decent pair of affordable maternity active leggings and this was my last effort before biting the bullet and trying the Blanqi brand leggings and I'm so glad I found these! Even on sale at 50% off Blanqi is twice the price of these when you include shipping costs.Definitely try these out if you are looking for affordable maternity active leggings. I will be living in these the rest of my pregnancy!
