I confess, in discourses where we seek rather pleasure and delight than information and improvement, such ornaments as are borrowed from [rhetorical handbooks] can scarce pass for faults [Arist. nobody uses fine language to teach geometry]. But yet if we would speak of things as they are, we must allow that all the art of rhetoric, besides order and clearness; all the artificial and figurative application of words eloquence hath invented, are for nothing else but to insinuate wrong ideas, move the passions, and thereby mislead the judgment.
John Locke

Canons of Rhetoric: Style
Style is created by repeating conscious decisions regarding sentence structure and diction.Or is it the unconscious, spontanious, expression of an authentic self? The subject matter, the audience's expectations and needs, the genre, the occasion, and the ethos you wish to convey should all be considered when selecting a style. The ultimate goal is appropriateness: Match the style to the circumstances. Don't curse in a church or wax sermonic in a bar. Clinical terminology is inappropriate for love letters; business letters shouldn't sound like lawyers' briefs.
Traditionally there are three styles, high, middle, and low. High style is reserved for elevated subjects at important moments in formal settings. The middle style is for business transactions and instruction, while the low style is how one speaks at home or among friends. In the table below you will find a list of the characteristics typical of each style, but keep in mind that the categories are not rigid; there may be elements of one that work in another. You can bring low words into a high setting to relieve tension, seem more approachable, or show passion. If you bring high words into low places you will sound pretentious unless you manage to sound ironic or otherwise amusing.

More About the Middle or Plain Style -- Brevity and Clarity
Cicero is said to have said that "Brevity is a great charm of eloquence." Shakespeare's Hamlet observed that "brevity is the soul of wit." There's no denying that getting the words exactly right is the goal of all effective communicators. The problem is, brevity is a very small target. You have to do a lot of rhetorical work to say only exactly what needs saying. And there are risks. Horace (BCE 65) said it well, "I strive to be brief, and I become obscure." Brevity perfected is silence. To use an obvious transformation of the most common topic of all, at some point less is less. Most of the time, however, less is more (in the sense of better).
Wiki has a classical chreia about the laconic style, the terse, blunt, and elliptical style made famous by the Spartans.
For most kinds of professional discourse, whether academic or business, the middle (plain) style is preferable. The plain style uses simple, direct sentences constructed in a subject, verb, object word order, using only necessary adjectives. The diction is common so that readers do not have to look up words or infer their meaning from the context. The goal of such writing is to convey information efficiently. The writer and his or her words seem almost invisible to the reader.
Below is a list of plain style editorial practices
As with all recipes, salt to taste.
Use the shortest meaningful sentence.
Keep modifiers next to the things they modify.
Use subject, verb, object sentence structure.
Most of the time, use the most important idea as the subject.
Use an introductory or prepositional phrase only if it is necessary for
a transition.
Use concrete nouns for subjects.
Favor active verb forms.
Use simple rather than compound verb forms.
Minimize the verb "to be" (search all and then eliminate any you can).
Rethink infinitive verb forms (to write).
Avoid nominalization -- turning verbs into noun phrases.
came to an agreement -- agreed
put one in jeopardy -- jepordize
an observation -- observed
a desire for -- desires
more...
on want of -- needs
a requirment -- requires
a demonstration of -- demonstrated
the indication of the results was -- the results indicated
take into consideration -- consider
we must enact a refusal -- we refuse
there was a decline in revenue -- revenue declined
Use positive rather than negative expressions whenever appropriate.
Minimize the preposition "of".
Eliminate empty expressions (sometimes when you can't quite think of what
to say, you fill the discourse with the written equivalents of "um"
and "er").
Eliminate self talk (like, "as said before" "that is to say").
Use technical expressions precisely and only when required.
Use metaphors only when necessary to aid understanding.
Don't mix metaphors.
Favor monosyllabic over polysyllabic words.
Use familiar words rather than foreign or old-fashioned words.
If you use a word your audience does not know, define it.
If you use a word in an atypical way, explain how you are using it, or don't use the word in that way.
Each word should have only one meaning.
Don't vary your terminology merely for variety's sake.
As a plain style writer, your job is to inform not entertain.
Spell out acronyms before employing them, unless they are commonly understood.
Base all new information on already understood information. Don't say anything
that your reader's don't have a context for. (If they don't know why you are
saying something, then they can't fully interpret it).
Develop only one idea per paragraph.
Ensure that the topic sentence of each paragraph is clearly identifiable and near or at the top.
Because rhetoric is the art of proving opposites, if one knows something of brevity, one should also learn something of copiousness. The Renaissance scholar Desideris Erasmus of Rotterndam wrote a book on that very subject: De Copia or of Words and Ideas
