I'm 70kgs and 1,63 so pretty far from skinny. That's why I was hesitant when getting jeans from a korean brand but they do fit. (30) In fact, when i'll reach my goal weight, it might even be too loose but the design is very elastic so i think that's good if you wanna lose weight and not have to buy another pair when you lose the excess kilos. It has a waist slimming effect too since the upper part acts like shapewear. Too long tho but I was expecting that. I'll just tailor it.
