5. "Why
Do Women Fuss So Much About X Trait (Makeup, Type of Clothes,
Shoes) When Us Men Clearly Prefer Natural
Beauty?"

The right question(s):
A) "Are they even doing it for men?"
B) "Is your idea of 'natural beauty' actually natural?"
First of all, most women's lives do not revolve entirely around
pleasing men. When I get new clothes, do you know who I expect to
notice? Other women and gay men.

OK, these women are in fact
probably dressing specifically to please men.
If you look at women's magazines, there will be a pretty woman on
the cover, and inside there will be tips on how to look like a
pretty woman, as well as some kind of pointing and laughing at
"fashion blunders." Not everyone wants to be a Marie Claire girl,
but every demographic has fashion do's and don'ts, and nobody
wants to be a fashion don't.

This seems to be a
"don't."
Most girls want to meet the standards of their style, as set by
their peer group. Goth girls want to look properly pasty. Female
ICP fans want to be the loudest, most hideous thing visible at the
Wal-Mart.
They'll do all of this even without boys in the picture. It's about
living up to girl standards.
Secondly, many of these "unimportant" things do actually go towards
making a girl attractive in the way men like. For example, the
right kind of shirt will flatter or even shape a girl's boobs,
something men have to admit does matter to them. The right
boot/skirt combo can show the good parts of a girl's legs while
hiding the fat/pasty parts. It's unfair to complain about her
fussing about clothes, while appreciating the result.

These two near-identical
everyday outfits have key differences in boob/leg display methods
that anyone can enjoy studying.
For guys that say they hate makeup, many girls use a certain amount
of makeup just to get to "normal." So girls with bad complexions
(a.k.a. white girls) use foundation just to cover up blemishes, not
to look like a painted whore. Or girls with tiny pig-like eyes (me)
need eyeliner just to give the illusion they have normal-sized
eyes. The point of daily makeup is to get from "ugly" (which
doesn't necessarily mean ugly, see above) to "normal." If it gets
to the point where you notice the actual makeup, it's either
overdone, she's going to a special event or she's in show
business.

Not totally "natural" looks
here, but Alicia Silverstone and Heidi Klum are
going about as light on the makeup here as celebrities ever go at
photo shoots.
