Approaching in the Club

Things you need to have first is TRUE BODY LANGUAGE,
because clubbing place you can not use words that are too long for the first time.

Then all you need is a few words - words
short like "Hi, What is your name?"
and the more you need is body language that shows
that you are a man who has value and high quality.
  Therefore, when he refused to meet with you.
The woman would regret her decision on that day.

The second thing you need to have is the correct FASHION.
  I am confident that at every club I've ever visited has a rule that 

you MUST DRESS-UP / DRESS-UP is A MUST. 

I'm sure you know that every woman who was in the club must dress-up with clothes and makeup.

If you come without looking cool.
They will think that you are not hanging out or you do not know how to take care of yourself.

Any of which is on the woman's brain,
  both are not a good thing for you.
