To go back to the original post, let me assure you, Yoda, that in the 1970s, a LOT of people were wearing bell bottoms. In fact, it was tough in a lot of stores to find straight-leg jeans (except for something like Levi's, which has had their classic straight-legs forever). Most of the bell bottoms were also low-waisted. I clearly remember getting a pair of wide bell bottoms from a place called InJeans in the 1970s. Five bucks for the jeans. Wide legs and a ridiculously tiny zipper because of how low the rise was on them.
And yes, I do think jeans started out as heavy-duty work clothes and then trickled their way down to the general populace... who now rip them on purpose to the point where they look ridiculous and cease to keep your upper thighs warm or dry in various types of weather.
And please, let's pass a law to keep men from wearing skinny jeans.
Also, shoulder pads were in everything women wore in the 1980s. Not just suits, but many/most tops that weren't T-shirts. I remember when shoulder pads went OUT of style, sitting around snipping them out of a bunch of tops and blazers. Good riddance!
As for hoodies, they've been around forever, but they weren't always called hoodies. We just called them sweatshirts or zippered/zipped-up sweatshirts (if they had zippers). Their use and name may have changed but their existence is much longer than those recent changes. If anything goes out of style, it won't be the clothing itself. It might just be that their usage morphs again.
I'll be glad when Ugg-type boots are completely gone. I don't mind them as cold-weather boots, but I dislike seeing people wear them as regular shoes when the weather is perfectly fine. I think of them as Ugh-boots.
