Classy clothes that don't fuck with my sensory issues?

I am a large (2XL) male that would like to dress better. But every time I find classy clothes that make me look more professional it's just a sensory nightmare. Rough fabrics, too tight in places, hard for the skin to breathe in, etc.

I need something other than baggy black t-shirts and soft jeans.

Have you men found classy clothes that make you look professional but is still comfortable to wear?
