Fads are a rapidly changing part of culture, and thank sweet baby jesus for it because these trends really need to just stay in their proper decades as warning for past fashion faux pas. And no, none of these should be worn ironically, either.
Platform thong sandals

Gold lame leggins
Unless you're in the top .0001% of people that can pull off this look (or this is still the '80s, which, last time I checked, it's not) these things just end up looking like legs squeezed into easter egg foil at a rave.
It doesn't matter how attractive, or famous, you may be, if you sport a mullet you look like a douche. I'm really sorry to break it to you like this, but someone really needed to let you know.
