The question of pubic hair styling is a pertinent one. The answer is, "It all depends."
Simply put, not all ladies —and not all lady parts and related skin and hair types— are created equal. Thus it's impossible to endorse any one style of pubic grooming for all, though I think we can say that smoothness is desirable, irrespective of all other variables.
The style should be suited to the individual. Some ladies have so little pubic hair that no real styling is called for. At the other extreme, some have some that is so thick and / or widely distributed that no amount of shaving, waxing or depilation is going to result in a smooth look or feel.
Some hair-skin combinations lend themselves more readily to certain kinds of treatment. Coarse, thick hair and delicate skin is a difficult one. Female pubic hair can vary in texture from silky strands to steel-wool stubble —and skin types come in an equally variable range of types.
In this man's opinion, ladies endowed with a giant triangle of pubic hair should not attempt the bare look. The results, even when freshly achieved, are never pleasing.
And the best overall look for any individual —even assuming ideal conditions in all other respects— can vary a great deal in relation to body type, size and proportion. The difference between pleasing proportions and not-so-pleasing ones may be difficult to put into words, but it's immediately apparent to the eye.
Details, details: an untrimmed bush, a trimmed one, the "landing strip" look, the bare look —each is potentially pleasing or not, depending on all the other related aesthetics and the way the woman carries herself. Perhaps the best pubic hair style is the one that least calls attention to itself.
And, truth be told, some people have no sense whatever of proportion in anything related to personal grooming, intimate or otherwise —and who call attention to themselves only by virtue of their utter lack of style.
All of these things are true for men and women and head and facial hair. We all know of many men with unaesthetic stylings, ranging from absurd comb-overs to jungly neck-beards, with many variations in between. We all know women who choose hairstyles completely unsuited to them in any number of ways.
And yet, at the end of the day —or at the crack of dawn, high noon, or the classic 5 à 7— it really does come down to personal preference on both sides of the equation. In the dark, all cats are grey and à chacun son goût. And à chaque con, as well. [Check your French dictionary here, if needed.]
