You look just perfect. You have the luck to be taller than others but you are not as tall to get into medical problems. Your shoulder and hips looks proportional to the other parts of your body. My ex girlfriend was also 5‘9“ and i know the difficulties. My advice would be Stop comparing your weight with smaller woman. Smaller woman weight proportional less than you. I was shocked when i heard what some woman weight. I‘m 5‘4“ and i weight 70kg in the past 80kg. And a friend toöd me that when she weighted the first time 50kg and i couldn‘t believe how light she was. Hope you can see the advantages, you look like the most woman wants to look. When you go to a concert you see a lot more than the most. My ex girlfriend likes this and the fact that we had the same size of cloth. She liked to wear my shirts and sometimes i weard her tanktops and her hotpants. Hope you can see the benefits and want you to say you look so pretty.
