Scientifically perfection in beauty comes from symmetry--It is an interesting topic to think about.
I was reading a book the other day and was reminded that EVERYTHING is attempting to achieve perfection in a symmetrical balance.
* The "perfect" facial shape is an oval. All other (heart, round, rectangle, etc) facial shapes have suggested haircuts/styles to give the ALLUSION of an oval.
* Overly concave and overly convex profiles have suggest haircuts/styles that give the ILLUSION of a "perfect" profile.
* Short thin people should avoid having large hairstyles, and tall thick people should avoid small hairstyles.
* The face should be three symmetrical measurements, hairline to brows, brows to tip of nose, tip of nose to chin.
* Small mouths should be lined outside the natural lipline, and highlighted (glossed) in the center of the bottom lip, to give the illusion of full lips.
* Overly large lips should be lined inside the natural lipline, and should be filled with matte colors, to give the illusion of less mass.
* Bottom lip should be slightly larger than top lip--both full. If one is smaller than "perfect", it should be lined just outside the lipline.
* If natural lipline is asymmetrical, it should be lined outside the lipline to fill in the missing line.
* If a nose is "too large" for the face a darker foundation or a lowlighter should be used to "shadow" the sides, and a highlighting shadow should be used down the center, giving the illusion of a perfect nose.
* If the tip of the chin is too pointy a lowlighter should be used to shadow the pointed edge, giving the illusion of a perfect chin.
* Eyes should be placed one eye width apart, eyebrows should begin directly above the natural eye corner, ending on the line from corner of the nose to corner of the eye.
* If eyes are too close together the eyebrows should be brought in past the eye corner, and darker shadows should be placed in the interior, giving the illusion of perfectly placed eyes.
* If eyes are too far apart the eyebrows should start a bit past the corner of the eye, and darker shadows should be used on the outer corners, giving the illusion of perfectly placed eyes.
* The female body should have a full bust, defined waist, and hips proportionate to the bust.
* Empire waist clothing gives small busted women the illusion of a fuller bust, thus large busted women should this style.
* Belted or darted clothing gives the illusion of a nipped in waist on those lacking the definition.
* Pants lacking back pockets give the illusion of a fuller backside.
* Pants with large back pockets give the illusion of a smaller backside.

Everything is meant to give perfection in symmetry. IT IS SO COOL! (Although it only shows that I'm imperfect, hahaha. My nose is too short for my face. However, I am proportionate in nearly all other ways, haha. My face is oval, my profile is correct, my hairstyle isn't small, my eyes are well spaced, I've got full lips, etc. ROCK ON!)
