What emptym said
I think the jacket cut looks very modern, actually. Maybe too modern. (Very short length)
Maybe they're commenting on the fabric? Is it threadbare? You used the word "ratty"
The aesthetics of that fit you posted could use some improvement
-Light grey jacket only really works with tan/offwhite/white pants
-Those pants are generously cut. They are also hemmed poorly. Puddling at the ankles. Looks awkward with that very "modern" fit jacket.
