A smile?
The voice?
The attitude?
Are men different in their criteria?
Or is it all about the pheromones?

I know it might seem a bit weird.. but I've got this thing about feet. I always look at a woman's feet.. if she's wearing nice shoes that's a plus. But even better if I can see her bare feet. I don't have a fetish or anything, it's just that if a woman has pretty feet that are obviously well taken care of, that means she probably takes care of the rest too. If she's got horrid feet with manky toenails etc, well it doesn't say much about the rest of her.

Apart from that, nice eyes and a warm smile..

the first impression all depends on if they know you`ve seen them.it`s more the first look.it`s not just that though i`m an aquairus and no joke from a significant sample of research 90% of my girlfriends or lovers and the best at that were all either cancer leos or giminis .id do or used at least do tarot and the like. and for pure heat geminis or cancer for me.

ok here is what i think wht important..
first impression:
lets accpet it we r all shallow being..so the looks is important,and i am not talking about a guy being attractive although it helps,,i am talking about the clothes u wear,your shoes(polished!),the way yu carry urself..the expressions n your face......and yea the main thing just be yourself..if u r not happy with wearing polished shoes,then all my theory can be wrong !.......but wht i think is that a men doesnt have to be attractive from outside(neseccarily)..if he is strong and masculine and knows wht to do from inside..then trust me he can be as hanfsome a gorrilla,women will love him...so tip ,work on your inside...be calm and confident?how?do yoga ,quit meet and smoking and do some hypnosis,lead healthy lifestyle....go towards your goals..achieve!and trust me ,when u r happy and conifdent with yourself others will see it too i hpe i could hepl,but at the end of the day,its wht i think is right and maybe a bullshit for you !

a good first impression is to make as little of an impression as possible whilst still making your existence know.

I think a good first impression is the result of a well established rapore. Some people can connect more easily with strangers than other people. But I think a good rapore comes down to bodylanguage and sincerity.
