Had high hopes for this but have to return it! I ordered skinny jeans/pants from vibrant in the same size 7 and those fit, yet these didn't. It is way too tight around my thighs and waist, I can't fully get it on. I am 135lbs, 5'2", US size 4 and usually wear a 25 in Forever 21. Perhaps if you are less curvy or less muscular this would fit. I'd suggest sizing way up but it's such a gamble.
