I've tailored t-shirts before I discovered a brand called 2tall which fits well enough.

I wore suits for the first 30 years of my life, but I can't stand them and they're terrible in warmer climates, I'm never wearing shorts with a suit. And that's part of it beyond the suitability (pun intended); there are unsaid overtones about wearing a suit that imply formality, status, etc. that I just do not want in my life.
