Here's a few list of what women look for in men.
1) Physical attractiveness
This signals to the woman that the man has good genes. While we cannot change our appearance, or at least not very easily, there are a lot of ways to make improvements in this area. Wear appropriate clothing. Invest in a pair of good shoes. Observe good personal hygiene. Have a favorite hair stylist to help you create your look. If you look comfortable and well put together, you'll nail this part very easily.
2) Youth and vitality
This tells the woman that the man is likely to live long enough to protect her and their family. She's going to be looking at how energetic and lively you are. Subconsciously, she's going to be looking at whether your skin and hair are glowing or if your eyes are bright or if your muscles are toned. My advice here? Exercise. It's good for your health and for getting the girls.
