Differs from person to person. For me, simple, decent/neatly dressed, polite, shy and traditional women attract me.
I will presume you are a female answering the question .Unfortunately there are two scientifically verified ways of attracting a handsome man. a)if you are a beautiful and young woman and b) if you are rich and.... and possibly c) if you are sexually available and a bit of a party girl .
A combination of a) and b) should prove irresistible, particularly if you have child bearing hips ,small waist , medium to large breasts ,large eyes,neat features and a smile. The inclusion of c) is an option according to individual preference.
However personality does count in some cases. Some handsome men have a brain and long for a true companion and can override their innate response to beauty if you are not so attractive. Sharing a common interest is always helpful,liking his mother even better. Cooking skills are still much admired.
Think carefully because looks are not everything. Some famous psychopaths were very handsome . e.g Ted Bundy.
In my opinion you would be better to try and attract a nice and warm hearted man who knows how to laugh, likes a good book and isn't averse to romance. If he also happens to be good looking then good luck to you.
