I'm 172cm tall and 49 kg. I was looking for clothes that would make me look less skinny while they're thin and comfortable. The waist is a little big for me but people with a normal size can wear M. I was thinking of exchanging it for S but I'm going to just wear it in case it's too small. A friend of mine also said it's pretty so I recommend this site to her. The color is cool. I usually do not wear long pants in the summer but I like these jeans so much because they're not too hot. The length is the added point as well.
