Maybe it was because she was at school, so the clothes she was wearing were quite normal. Maybe she just likes this more literary lady style. I wonder if there are any new breakthroughs in recent years. Anyway, you can wear clothes as long as you are happy and like, and you don't have to care about other people's comments. Besides, she is still young, and this style suits her very well. If you take that sexy style, you may lose her original sense of youth.
And it is also very important that her temperament needs to be improved now, and she may not be able to control other types of clothes. In fact, looks and clothes are secondary, mainly temperament. Temperament needs experience, and it is also closely related to her inner cultivation. So even if the appearance is sweet, you can't wear that charm without temperament. If she wants to show business, this style will not have any advantages, and it is no different from other stars.
And if you want to enter the show business, you'd better ask a professional stylist to help her design. It is difficult for her to get a foothold in the entertainment industry with her own dress taste. As long as we help her find the direction of dressing, the rest will gradually become influential by time accumulation.
