From what I've been looking for and from my experience in general, I can give you some tips on how to change so you can look different from other men.
The truth is that when I go out, I see people with simple outfits that make them look like geeks. And for women, when a person has little or no experience with women or has no social life, is a huge turn off.
Here are some advices.
Step 1: Dressing
Clothes that do not fit your body
Many men do not wearing clothes that fits well on their bodies, and they are preferring a larger number. A cheap but well fit T-shirt, looks much better from a more expensive but not so well fitted.
Clothes with different colors or not matching
Our clothes should match each other, but also with the color of our skin. For example, if you are white, prefer dark colors, while someone who is black should prefer light colors.
Also, the clothes should not have many colors or colors that do not tie together. As a tip, it is best to take with you and someone you trust its opinion on dressing. A simple tip is the color of the shoe to be the same as the belt.
Out of fashion clothes
Remember, our clothes should be in fashion. It is advisable not to buy a full amount of clothing once a year, but every three months, for example. Also read magazines in fashion to get an idea of what is happening in every season (for example, I read Men's Health corresponding column).
Bracelets and watches
It is good to wear a good bracelet, a chain or a good watch. It changes your style directly from having "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 to ask for his advice. Prefer a hairdresser (it is good to be gay) and not a woman. If he's gay, it's better because he's going to get you a way to look sexy than a coiffeuse who will prefer something safe and classic.
Also, the hair should be shortened from the nose and ears. Take a special machine from any shop.
Our breathing is an important factor. Our mouth should not smell bad. Avoid eating foods containing onion or garlic, and also have some flavored chewing gum. Also, frequent brushing is a must.
The cologne is also something you should wear everyday. Also after bathing, it is advisable to use some deodorant for armpits and whole body in general.
Step 3: Posture
A few simple tips. Do not make quick moves. Do not talk quickly but slowly and clear. They will understand you better.
I was doing it and I tried to stop 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 why I never asked.
But they looked strange at me as I waved like a minister who gives a speech. CUT IT. Also avoid to sit down or stand 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 in order to hear you.
Always keep eye contact with people, especially with women. Sometimes you have look and elsewhere, 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 right or left.
I hope this information is useful to you. I learned most of them by observing other guys, observing others when I was talking (especially in grimaces and movements) and by reading tips from the net.
