I have tried peacocking myself when I heard that other guys were doing it. I did this maybe a couple times, just to see if it worked.
I felt ridiculous, and was totally incongruent with my personality when I went out.
But we all know that women pay attention to fashion, and like a well-dressed man.
I noticed that some of my best pickups occurred when I was in my workout clothes, or I was wearing something really basic - like jeans and a tanktop.
I'd see muscled-up guys wearing revealing spandex, or super-tight shirts at the club, and women definitely did not respond well to this.
This make me think... that maybe this is not on how much the clothes cost or how flashy they are...
I guess there is something else going on.
There are two things going on. This two things must be manage or balance.
First, avoid seeking approval from women. You are toast, if a woman can tell you that you are trying to impress her and make her like you.
So if you come like you got dressed with a purpose of getting women's attention, they'll see you coming a mile a way and put up their defenses.
You shouldn't have to look like a pick up artist.
It's better to dress modestly, and not put too much thought into it.
However, you need to present yourself in the best way you can and not to look sloppy.
This comes back to self-expression.
You already have a sense of what kind of guy you are, what your "scene" is, what you think is cool.
Don't change that.
Instead, develop it, with these simple tweaks.
This isn't a rocket science. Wear colors that appeal to your skin tone and hair color. Go to an upscale men's clothing store, and ask someone about this. Or look online.
Next thing, make sure your clothes are clean, wrinkle free and reasonably updated. A woman shouldn't have to worry about bringing you around her friends.
Most of all, be sure that your clothes fits well, they BRING OUT YOUR MASCULINE PHYSIQUE.
Wear shirts that narrow your waist, and square your shoulders.
Have your legs look long and thin by wearing pants.
Wear shoes that make your feet look big and well-formed.
Groom yourself - nose, neck, and ear hairs. Get a nice haircut. Shave, or don't, but figure out what looks great and take it all the way.
One other piece...
Accessories should adhere off you loosely, and have a look of a small decoration that says, "yeah, I can fuck."
Make out for your intuition with this one. I don't want to say too much because that's a whole other topic.
