If I'm really dressing up (i.e. wearing a suit), I've always preferred a traditional look. Something you'll never look back on and go "god, what was I thinking?"

On the waistline; I tried on a pair of repro M42 pants with the high waist that's goofy by modern style.

By god, those are the most comfortable pants I've ever worn, they don't rub your hips and they're so roomy. Waistbands should be up at your waist.

1910s and 1920s surely had the best style fashions.

I also like the early postwar era; the late 1940s-early 1950s, but I agree with you about the 1910s-20s.

This.. Surprisingly is a pretty helpful guide

All great info, can confirm.

But I also just want to stare into those eyes longer~

I'll admit that I sometimes like a fancy painted tie and a flashy pair of shoes if I'm going to a party, but I certainly agree with your "formal" notes if I'm going somewhere more, well...formal. It all depends on the event that I'm dressing up for.

I'm a bit of a Vintage Clothes Enthusiast, and I enthusiastically agree that the older suit cuts are not only more comfortable, but also more aesthetically pleasing, for the same reasons that you so well outlined with this submission.

While I was in college I routinely visited the old-clothing shops in search of nice suits/jackets/ties/etc. I once scored a salmon pink tweed suit coat with gold and silver metallic thread woven into the fabric.
I loved that metallic pink coat. It suited my rockabilly aesthetic very well, and what's more, it upset the right people when I wore it to church.
