Pleated trousers with a slight taper is where it's at for me, personally. A nice belt, a tucked in roomy, but not too large shirt. I'm good.
Bootcuts really only look good while wearing, ya know, boots. That said, if you're gonna rock them, go hard and get those Wrangler Wrancher or Levis 517 polyester ones that are only sold at Western Wear stores. Bellbottoms are for first year college hippies and cosplay.
