From what I've seen through my research and my experience, I can give you some tips on how to change yourself so you can look better than every other man.
The truth is that when I go out, I see people who look like geeks. And when a man has a little or no experience with women or has no social life, it's a huge turn off for women.
Here are some advises I can give you to improve yourself.
Step 1: Dressing
Clothes that do not fit your body
Many men do not wear clothes that fit well on their bodies, and they choose bigger clothes. A cheap but well fit T-shirt looks much better than an expensive but not so well fitted T-shirt.
Clothes with different colors that don't match
The color of your clothes should match each other, and of course with the color of your skin. If you are white for example, choose dark colors, while someone who is black should choose light colors.
Also, the clothes should not have many colors on them. As a tip, it is better to go shopping with someone you trust his opinion. A simple tip is the color of your shoes to match your belt.
Out of fashion clothes
Remember, your clothes should be in fashion. It is better to avoid buying a lot of clothing only one time each year, but go for shopping every three or four months. Also, read fashion blogs and magazines to get an idea of what is happening every season.
Bracelets and watches
It is good to wear a good bracelet or a good watch. It changes your style and it's better from "bare" wrists. My watch is this.
Step 2 : Grooming
Our hair is a sign of how we treat ourselves. It is advisable to go to a hairdresser and get his advice. Prefer a male hairdresser and prefer a gay one. If he's gay, it's better because he's going to get you a way to look sexy than a woman who will prefer something safe and classic.
Also, the hair should be shortened from your nose and ears. Take a special machine for that.
Our breathing is an important factor. Our mouth should not have a bad smelling. Avoid eating foods containing onion or garlic, and also have some flavored chewing gum with you. Also, brushing is a must.
The cologne is something you should wear every day. After bathing, it is a good idea to use a body deodorant.
Step 3: Posture
A few simple tips. Do not make quick moves. Do not talk quickly but slowly and clearly. Everyone will understand you better.
I did it a lot and I stopped it. Also, do not do many random moves with your hands, something I noticed on me too.
I noticed that the women I spoke with, every time I raised my hands while speaking, they looked at me with suspicion(?), fear(?), wonder(?) I do not know exactly because I never asked.
But they looked strange at me as I waved like someone who gives a speech. STOP IT. Also, avoid being sitting down or standing in a closed body language.
Your voice should be deep and come out of the diaphragm. As a tip, imagine that when you are talking to someone, he's a few steps away from you, so you have to raise your voice a bit in order to hear you.
Always keep an eye contact with people, especially with women. Sometimes you have to look and anywhere else, so you do not scare her, but never look down. That is to look at her eyes for 9 seconds and 2-3 seconds at her right or her left.
I hope this information is useful to you. I learned a lot of ideas just by observing other guys who had a very good style and by reading tips from various magazines for men.
