Wearing thin steel rings can make the chest look smaller. Chest development is normal at this age, so don't worry too much. It's just that your height seems a little small and your chest is too big to feel uneven. You can try to grow taller, so you won't feel too big. Many girls are crazy about breasts, but breasts are just a big deal. You still have a year to grow up. Generally, girls don't grow much taller after they are eighteen. Pay close attention to this older height. If it really doesn't work, you can consider using equipment to pull it up, but you should pay attention to ensuring safety and don't pull yourself out of the predicament. In addition, supplementing nutrition at this time is a very important way to grow taller. Don't go on a diet too much, but be full. In this way, you may have a height and a better body proportion. Eating fat these two years is nothing. You can lose weight after you are twenty. Losing weight will not reduce your height, and then you will be a beautiful woman with a standard figure.
