It means thin and scrawny body.

On removing "seedy", see comments at 見すぼらしい (which some J-J's use to help define this entry).

貧相 contrasted directly with デブ（fat), with images:
デブ見え？貧相？

Image search yields lot of body-type, fashion, and food-related images. 

Daijs and sankoku give the same two sense.  The first is "literally looks 貧乏", the second seems like the metaphorical use in [2] that is tossed around in fashion magazines. While I find little direct support online for "impoverished-looking", it matches  daijs "いかにも貧乏そう", and disambiguates "poor-looking". 

daijs and sankoku would both give 福相 as antonyms for my suggested [1]. Given the relative rarity of 福相, I'm not sure we should do that.  The gloss on 福相 "happy-looking" could probably be improved.

While "shabby" appears in various refs, I am suspicious. It's used to describe clothing in English. "shabbily-dressed" could appear in [1], maybe, but in [2] it would be at odds with "scrawny".  In all the fashion mags 貧相 indicates the body type, not the newness or quality of the clothing. 貧相 doesn't seem to be applicable to the clothing itself.
