What physical characteristic draws YOUR eye, first and foremost, before any other?

For me, it's a toss-up: Eyes, cheek bones, jawline, collar bones, and sternocleidomastoids (the muscle that runs from behind the ear down to the collar bone).

Be as clean or as dirty as you want.

First thing I notice about a woman...... well..... that is hard to say. It all depends on where I am in relation to the woman when I notice her.

If I am sitting on a bench in the park and she goes jogging by, her legs and tuchas are most likely to draw my attention. (I am a legs man)

If I am at a gathering of people and there is a new girl in the room, and I notice her from afar, face and hair (I like all colors, but dark auburn does have a place in my heart).

If at same party my original encounter of said woman came as an introduction (face to face encounter), visually -- eyes (no specific color required, but a glimmer that draws me in) and hair (see above), but I will also notice things like speech pattern (sound and content. altos are easier for me to listen to, and smart girls are a serious turn on for me), and laughter (I like girls who can laugh but I also have to make sure I am not encountering The Nanny 8-) )

At first it would be Her Eyes and her smile 'lips, teeth'

Typically, her asset she brings out. It can be eye, mouth, breasts, hips, legs...

I agree with luke. What I notice first about a girl, it's often what she decided that I have to notice first. For the rest, I look later ... more discreetly.

Eyes, ass and legs. Depending on the angle when I see her.

Her hair.

I love long nice legs, so if she got nice legs, i will notice her!!

Is she wearing clothes? damn...
Seriously running Daz for 4 years while looking at other real people I might put in my render art What I notice first is her age and how well she's held herself together; Mid twenties to 40 for daydreaming. What I am looking for
or what hits my radar causing me to notice the woman is what makes her stand out. Ass, tits, legs, cheekbones. I have worked in customer service a long time so I've learned to study my mental snap shots.
