If you want readers to clearly see what you are describing in your writing, you must use nouns that are both concrete and specific.
Clothes is the example of a vague noun.
Work clothes is a better choice, because it’s specific, but it’s still not concrete.
A red, black and grey flannel jacket, a pair of blue denim jeans and heavy caulk boots is a vivid description of clothes worn by a lumberjack.
Can’t you just see him?
So, if you are using vague nouns in your writing, ask yourself if using a more specific one would paint a more vivid picture, and if the answer is yes, then change it!
