First: because the figure is too thin, there are no chest muscles, and the shoulders are not wide, the clothes you can choose should not be too narrow, and it is better to leave a certain degree of looseness.
Second: You can choose clothes with lighter colors to have a sense of expansion, which can make people look a little "fat". If the clothes are loose, you can also ignore the color.
Third: Because the neck is long, it is best to choose high-necked clothes, or shirts, collars, lapels and other clothes are better.
I can think of the above for the time being: please refer to it.
