First Stills From "Answer Me 1988" Feature Hyeri Rocking the 80's Vibe

I was one of those children that just got the end of the 80's style so a lot of it is not exactly in my memory.  And probably for good reason since looking at these stills makes my brain hurt.  However in true Answer Me fashion, the cast is rocking the look of the time.  

Here is Hyeri in high wasted jeans and bobbed hair and obviously in school.  Makes me wonder when the current trend of school uniforms came about.  "Answer Me 1988" is set to air in October following the current hit "Twenty Again".
