Oh the Shein bashers are out 😂. I get my clothes from there, or supermarkets, because its all i can afford. The quality has changed enormously since Shein became mainstream, stuff is as well made as any uk high st store and lasts perfectly fine. Its pure snobbishness to look down on Shein as "fast fashion" - some people might treat it that way but many dont. I dont give a flying fig what all the toffee nosed Cos or Arket customers think.
also - yes of course its fine for a fifteen year old. If she feels comfortable wearing it then she should be allowed to wear it. We should be policing the dirty perverts who are sexualising 15 year olds not a girl wearing a dress she likes
