Ok, I'm really tired and bored so I'll bite...
I say that when asked "How are you doing?" unless it's in reference to your health, can not be answered, "I'm doing well."
"How are you doing?" That pretty much IS inquriing about one's health, whether physical or otherwise. Plus, the "doing" is what's in question and "doing," being a verb, needs to be described by an adverb. "Well" is an adverb and should be completely acceptable as a modifier of "doing," making "I'm doing well." a valid response. (?)
Example:"How did the test go?" It could not be answered, "It went well." As that would be improper according to Webster's. Instead it must be answered, "I did good."
Because "well" is not being applied to a person(s), but rather the test-going, it doesn't need to be in reference to health. As for "I did good.", I think it would indeed be "I did well.", based on adverbs versus adjectives. "I am(+doing) well/good." is where the problem lies. I could probly type a thesis on that (and probably have half of it be wrong) but I'm falling asleep so I'll try to keep my babbling short(ish).
...Thus, The dress fits well and looks good."
Correct, because "well" is modifying how the dress fits (a verb) and "good" is being applied to the dress itself (being a noun). "The dress looks well." would mean that the dress actually has a sense of sight and does the action of looking itself. Just like saying "I feel well." (often referred to as "over correcting") means that you are adept at feeling things: like boobs.
Feel free to point out any glaring faults in my "logic;" I've made a bigger *** of myself before.
