We're bringin' back capes and cloaks.

To prevent the obvious reference, the trend will be called, "'No capes' only applies to superheroes."

Bring back short shorts for guys. I'm sorry about the occasional accidental testicle shot, but they are very comfortable and not always gay.

Made a different comment. Deleted it. Had a better idea:

Those loose, light clothes that people in middle-eastern cultures still wear as traditional clothing. There is a reason they came up with those when they did. Elsewhere in this thread another peep was complaining that men don't get to show enough skin and specifically citing heat as the reason this annoyed them. I say fool. Showing skin will not save you from the heat, especially as climate change continues to cook the planet. It will, in fact, make it worse.

If we are to survive being cooked alive by the sun, we will need to cover up, as the people who inhabited arid-and-extremely-hot places for centuries have done.

Actually, since the Dune series got an injection of popularity with non sci-fi nerds thanks to the Denis Villeneuve films --

-- We could call it "Fremencore". Integrate some futuristic aesthetic influences so people don't think it's cultural appropriation.

I want it to be super cool to wear really old but well maintained clothes...

I want people to be all like "oh sorry, this is only 3 years old, I had nothing older to wear"

End the "color of the month" crap and all the hot fashion trends

I'd want to take the fedora back from the incels and neckbeards. Other currently out of fashion hats and caps too, but the fedora has been too monopolized by inceldom when it's a perfectly serviceable hat for folks who wanna dress up from ball caps.

Power Hatting.

The style is expressed by trying to have the most powerful hat; by which I mean the most big, intimidating, unwieldy monstrosity of a hat possible. One that's so big and complicated that you can barely hold your head up and might even need shoulder bracing.

The purpose is to invent a fad that is hilariously stupid to watch people try and follow so that I can point and the laugh at them all the way to the bank. Because fashion is stupid, and money is useful.

I don't know what I would call it, but I have been wanting a more furry style for quite a while. Like hoodies that have ears on the hood (or hats with the same), things that are actually fuzzy and such, tail belts that actually work as belts, etc. Not just character designs on t-shirts or just using furry art on the clothing.

Go back to weekly baths and wear the same outfit every day without washing. Would benefit the environment, reduce slave labor in the fashion industry, and keep people away from me.

I would be happier if plastic surgery, instead of always being aimed at making people closer to all the same, was used to make us look different. Elf ears, horns, tails, big noses, different shaped faces, neanderthal brow lines, creative changes. That is the style I'd like to see happen.

Also, since I'm in Florida, fancy parasols.

Business Flambouyant

Take your business casual fit. Make the khakis skin tight and stretch them up around your waist, maybe add in a horrible sash akin to a novelty tie. Widen the sleeves of the shirt, make em a bit poofier without going full swashbuckler. Widen the collar. Make the toes of the loafers a bit pointier, and give the heels a good inch of platform. When outdoors, a diagonal hat is optional.

I think that we're kind of not answering OP's question, since exactly one person as of this writing other than him has a new style, and everyone else is nostalgic for older styles that people aren't wearing any more, so I hate to add to the "nostalgia" pile, but I kind of miss the denim jacket from the 1980s. Sometimes quilted, if you needed extra heat. Was durable, though not appropriate for precipitation, since it couldn't shed water. I don't really live where I need heat, but I remember really liking them. They were comfortable, very tough, not very expensive, and I liked the look.

Jeans have never gone away since they showed up in the 19th century...but the denim jacket seems to me to be a lot less common.

Today, I'll sometimes wear a loose, very light, unbuttoned denim shirt over a T-shirt, which is about as much as I need, heat-wise. This kind of thing:

Light denim shirt:

People certainly wear those all the time. Kinda miss the thicker, tough denim jacket, though. Haven't had one for ages. And I didn't just like wearing it myself, but like how it looks on others, and it works for both genders.

Don't really understand why denim pants had so much more staying power and universality than the denim jacket. They seemed like a good pair.

A trend that is focused on turquoise and teal colours, maybe mixed with white to represent sea foam. I would call it "Neptunian" relating to the Roman god of the ocean! 🐚

Anything making n95s, kn95s, and kf94s more common.

Maybe mix it with one a them big cyberpunk too many pockets jackets

For a bit of non-traditional men's fashion, I want a a cape/cloak made of nice cotton, one that is swooping with clean lines. You can wrap it around you for a bit of warmth on a brisk day, or let it hang open for a breeze.

You can have informal, casual ones for out and about, or formal ones that have a rigid collar and can be affixed in front like a traditional jacket.

They're comfy, protect your skin from sun damage, can be worn in layers, and if you're in a pinch for tourniquet cloth, plenty of fabric!

Can I make t-shirts + shorts + flip flops become a new formal wear if it's fashionable enough?

As for something more fashion-y, for men, I'd make something with lots of freedom of movement, aesthetics as pure afterthought. I hate stuff that shows my belly whenever my arms go up or legwear that won't let me sit, crouch, stretch or anything without feeling like my fat ass can rip the fabric at any time.

Mens formalwear needs a complete overhaul. Lapels and ties change width, but a suit is a suit is a suit and has largely been unchanged for decades.

I don't know what to call a change I'd like to see, something different.

There are Japanese street coats with wide, tall collars that are almost hoods:

Some formal equivalent of that?

My fashion dream is that everyone is wearing sweatpants and comfortable clothing or whatever the hell they want.

With increasing temps less wool, more short pants with long socks, coats replaced with lighter material sweaters and jackets, and please some hat option other than baseball cap or newsie.
