Use metaphors to illustrate (and deepen) your descriptions. Also, contrary to the advice above, perhaps it's a lesser crime to reuse the same basic plain-spoken descriptors than it is to go out of your way to avoid it by substituting flowery esoteric language that draws far much attention to itself and interrupts the flow of the narrative.
Indeed. I have been a fan of H. P. Lovecraft's work (less so the man) for decades but, wow, someone really needed to hide his thesaurus. The guy could be the living definition of "flowery esoteric language" when in the right mood.
Being someone with a bad tendency to edit on the fly, I will often catch and fix overused language as I go. No thesaurus involved usually, unless I am really stuck for an alternative. Often, I can ditch a word or two in places, or reword things. But I don't really have a method, just a tendency to catch things as I edit.
