I'm 165cm (5'5) and I usually wear size 36 (US 4) or S.
Louise Jumper in Light Beige: size S. I really like it, but I’m going to size down. Really love the combination with crème/ecru trousers.
Damon Trousers in Ecru: size 36 (US 4). I was really excited about these trousers since I read some reviews they would be perfect for petite girls like me. But I am not so sure the length is fine, looks either too short or too tall. Love the color and the quality!
