Hello, first of all, thank you for your interest in our product. The tracksuit bottoms you have reviewed have **"Barrel Fit"** pattern. Due to the structure of this pattern, the leg parts have a curved, draped and wide cut, so it will certainly not stick to the body. When you choose **size S** for the height (166-167 cm) and weight (59 kg) measurements you specified, the product will display a loose and flowing stance on you exactly as you want, due to its own cut, it will not stick. If you want a much more extra loose/oversized look, you can also consider size M; however, size S will easily meet your loose fit expectations. We wish you pleasant shopping. Madmext Team
