> The problem that I'm increasingly encountering is that everything (up to XXXL) in shirts is too small for me. There's nothing that can be tailored to fit.

> Jeans simply don't tailor well on account of seams and other factors. Slacks can be, but again, you've got to have the material to start with, and today's "skinny" styles don't.

I'm curious. What are the types of stores you shop at? Although I'm sure styles have been slimmed down across the board, there are plenty of stores I see with regular fitting clothes.

and FWIW, jeans tailor fine usually, you just need a tailor that knows what they're doing and obviously cost may not be worth it.
