First things a girl notices in a guy

It matters a lot for any guy, what a girl notices in a guy at first. Actually girls notices a lot, from your shoes to perfume to your eyes. But don't worry here are few things which every girl notices first.

1. First thing any girl notices is definitely looks, who said looks doesn't matter, but it's not necessary to have a look like Hrithik Roshan. You should have a cleaned, groomed face with a smile, that's enough. After all we are all god's creation.
2. Girls are very sensitive about hygiene, nails, hairs, or your body odour. In the brain of females the number of cells are approximately 1.5 times than males, so may be the odour of body can irritate her. It's not difficult to bath once a day, ok once in two days should be must or apply some deodrants. you should take care of your beard and nails, they are well trimmed or not. If you look like a monkey not only girls, everyone will try to keep a safe distance from you.
   
3. Now comes the dressing style, it's very necessary to dress well not only to attract girls but for confidence too. If you dress well you will not loose your confidence. So, you should not wear dirty or shabby clothes with stretch on it. Clothes should fit you, not too much tight also. You can understand it through the picture below.
4. After the physical appearances girls notice your talking style and confidence, that doesn't mean you have to throw your hands and move like a filmy hero while talking, just be humble and confident. Now over confidence or rude behaviour can kill your first impression.

5. Eyes and physiques are also noticed by a lot of girls. They find eyes attractive which are little green or brown in color. And ofcourse a good built muscle can attract them, any girl will mostly prefer a man with good physique over a fat guy. I mean you will find the upper image of Hrithik more appealing than the lower one.

As I said earlier girls notices everything but these are the points which most of girls notices first. You don't have to pretend to be like this, you should bring the positive changes in you.
