Posture:
I do slouch sometimes, though not always (I usually have good posture while walking/standing). When I sit, I either lean back so much I look totally disinterested (I probably am) or, if I get into a conversation I'm into, I slocuh forward and pull my legs up onto the chair and start sitting indian style.
My hair:
I try to keep it not-too-short not-too-long and basically all my haircuts are just trims, nothing fancy. I clean it every other day in the shower (heard that's better for it and it saves time), and do not dry it, do not comb it, do not brush it. Sometimes I use my hand to put it in a position I like more.
Clothing:
I try to match colors/styles well so I look presentable, but I also like to be able to get ready fairly quickly. I also like to mix casual and formal, so I own a lot of button up shirts (whenever I wear a sweater I like to but a button up under it), have a few vests that I occasionally wear, and about 75% of my jackets are blazers, and most of those that aren't have lapels. Every so often I like to wear a full on suit, usually I do so some random night when a bunch of my friends and I go out (or when it correlates to a special occasion). Sometimes, however, I will wear the same thing a few days in a row (especially pants, which can go longer), particularly if I haven't seen anyone I know while wearing those clothes (obviously, I'll change if it gets visibly dirty). In warmer seasons, it's almost always a t-shirt with some odd picture or reference or a very dry joke on it and jeans. I rarely wear shorts. I also like belts and have worn the same watch virtually every day for about 5 years..
I generally have one pair of shoes at a time that I'll wear almost every day for about a year (until they are clearly falling apart), and a secondary pair for when the first is too different from the rest of my clothes, and a pair of dress shoes I rarely wear. It has been probably 8-10 years since one of these pairs has had shoelaces.
Facial Hair:
I have had a beard, earlier this year in fact (March-June). It's rare, though, and that's only the second time I ever tried to grow a beard (the first was over summer of 2006). I generally shave every four days or so, so I often look a bit scruffy.
Cleanliness:
Shower every other day, generally try and use a facial cleanser every day (some days I miss). Obviously, brush my teeth at least twice daily with rare exception.
But the other points are spot on.
I admit I slouch quite a bit, but otherwise, I do pay attention to my appearance: clothes, makeup, hair. I have noticed that I only get super creative about clothes every once in a while. I buy stuff I like and then throw it on without thinking much. I could never pay enough attention to be a trendsetter or personal stylist.
