【Shabby】 ,  【dilapidated】 ,  【dingy】 ,  【faded】 ,  【seedy】 ,  【threadbare】  refer to the appearance of persons and of things and mean showing signs of wear and tear.

【Shabby】 applies to persons and places and suggests a lack of freshness or newness in those items that contribute to appearance; sometimes the term applies directly to the things, especially clothes, which so contribute. Poverty is often suggested as the cause of this run-down condition but various other causes (as neglect or indifference) may also be suggested.

【Dilapidated】  (compare dilapidate under RUIN ) implies a worse appearance than  【shabby】 , usually suggesting a broken-down or tumbledown condition resulting from neglectful lack of repairs or from careless abuse.

【Dingy】 applies to what is no longer fresh or new in appearance and shows the effects of gradual soiling that dulls the colors or dims the brightness.

【Faded】 also implies lack of freshness but it connotes the loss of vigor or brightness that shows that a person or thing has passed its prime and is revealing signs of drooping and withering.

【Seedy】  does not go so far as  【shabby】 in implying deterioration and lack of freshness but it does suggest some loss of those signs that marked a person or thing as strong or at the peak of value and usefulness.

【Seedy】 is also used in reference to a person who feels himself not really sick but not up to the mark.

【Threadbare】  (see also TRITE ) in its basic use implies such wear of fabric that all nap is worn away and the threads are visible, but often this basic notion is lost and the emphasis is on the 【shabby】 state typical of or the fact of extreme grinding poverty.
