These jeans are amazing! The quality is very high, the material feels durable, and they are so comfortable to wear. For reference, I am 160 cm tall and weigh 56 kg. I ordered size Medium, and it fits well. However, if someone has similar measurements and prefers a more fitted look, I think size Small would also work. If you prefer a little more room, a looser and more comfortable fit, Medium is a great choice. It really depends on whether you like your jeans more fitted or slightly relaxed. I’m very happy with this purchase and highly recommend them!
