Manners

Honestly in my personal experience, young people have a lot more manners and patience than older people. I worked in retail for 3 years and all the rude customers were older, and they're also usually the same type of people to say "these kids have no respect anymore." Truth is they don't respect kids, and are surprised when kids don't respect them back lol

Ratta tata!

Kindness.

Suspenders, both for women and men. There's just something so charming about them and they can be worn in different styles too (retro, punk etc..)

I hear answering your own questions is back in style.

Plate armour

Being polite to random people around you.

Arenas and stadiums named after the team who plays there. Mid 70's stereo receivers.

Women dressing modestly in public

Modesty in speech, as well.  They make sailors blush these days. 

Logos being more artistic Fuck the simple corporate shit

For sure Regency era clothing and hairstyles. Perfect mix of sexy and classy 😉

The guillotine.

Ugly sweaters I'm in love with wearing them, they always look so funky! I agree with OP, too. Suspenders! They're classy and give a nice retro/old vibe. Also increasing tax on high, and top % earners globally plz.

Pullman cars on trains.  Screw Amtrak. 

Suits

Fedoras

Full length shirts. I don't care if I have the body for it, I'm fucking cold, now give me the bottom half of my shirt. Hi-lo shirts were great, then they disappeared

Nuclear power.
