This fashion is for over-50 year old Lao girls. It looks very old old fashion, and I don't think Lao people can wear this in their real life.
If a female is over 50 years old I would call her a woman, not girl.
Are you a girl and you don't like this style? Not everyone will like the design but hopefully enough for the designer to make money and continue designing.
I think this style is simple and practical. I think it is nice.
