There is one important reason why a man choose to trans gender or cross-dress because of his feminine attributes which he is possessing from his birth and more over he is suppressed as a child and at that point of time his curiosity about having feminine attributes was not present at that point of time. Now we dont have to focus on the reason why man experiments with himself and want to rediscover himself in the best possible natural manner and realistic too.

From childhood women are taught how to show feminine attributes whereas as in contrast to men are taught with masculine attributes such as men are not that caring compassionate as if compared to women. So to behave as a genetic female its not so easy men should show all the female characteristics and should mould themselves in women psyche

A man whosoever tries to wear a woman dress and want to be a transgender is just that a man is dragging himself. Because a man who understand easily the women nuances and if he clearly knows all the techniques how to behave like a female in public he will not face any embarrassment in public areas
There must be a close attention paid to the make up, shoes clothing,hairstyle,finger nails, body is properly waxed or not. These all properties should be fulfilled if any male wants to cross dress because to behave like a woman blending is necessary and after blending its not so easy.

Now if we come to see that what is the most important detail of all (answer is the face) the face gives the most important detail of all and especially the yes tell everything. Its been rightly said that eyes are the path to one soul... you might do well in observing a women face, study the face of a woman what is the shape of her face its totally different from men and after analyzing it you can easily make out that what type of make up trick you should follow to be look as a transgender.
