I am 160cm tall, around 66 kg. The website recommended me to take size M, so i did. I feel like i should've sized up, because they're WAY too tight. I have 105cm around my hips and 72cm in my waist. I'd prefer more accurate size guides... they're so tight i thought it's gonna rip in the bum scrunch. I'll definitely need to lose some weight before actually wearing them.. but overall, i am satisfied. The material is high quality, shaping the body well. But the size guide definitely needs to be more accurate..
