Adolescent girls had better wear comfortable clothes, which involves physical hygiene. If you are not particularly fat, you will gradually lose weight. I mean, with the development of your body, the so-called girls are all S-type, about 18 years old, and generally your figure will be much better than that of adolescence. I guess you must be young to wear school uniforms, so you should pay attention to comfort and physical hygiene when developing. I study fashion design, and I know a little about it. I wish you happiness.
