They were called "hypercolor" then and I admit I owned one though I rarely wore it. After about 3 washings it stopped "hypercoloring" and just was a drab grey.
Now they are back and as tacky, and crappy, as ever.
Thank you American Apparel for bringing back such a crappy 80s fad. You can be such a douchebag-like company and this is just another proof of that.
