Ouch, that hurts about the trousers! I actually love how they fit - they are not so baggy really, my legs are just that thick. Or are you just talking about the fact they are plaid trousers?

Patterned odd trousers are okay for a dandified look i guess

It's not the rope and pagoda per se, but the combination of the rope, convex shoulder and aggressive lapels (mitigated by the blue tie and more appropriate square here)
It's a statement jacket- industrial- flat planes and angles and bumps, and IMO won't play with informals like those trews etc
