Thought you might say something like that. Yes you can act tall!!
Allow me to elaborate, if you are of smaller stature than the average male, you can make yourself look bigger by the following;
1) The clothes you wear
2) The stance you adopt when you talk to people
3) The way you walk
1) The clothes you wear---- In other words the clothes you wear effect the way you look. Do not wear baggy trousers, these make you look shorter. Wear decent fitting jeans the lighter the denim the better. Shirt wise, vertical stripes make you appear taller than you actually are, the more fuller figure guy would also use this trick to make him look thinner, by making you look taller it makes you wear your weight better anyway I digress.
2) The stance you adopt when you talk to people is very important and is sometimes the hardest to utilise. For example when you are standing talking to people, stand a little bit back so that you don’t have to look up at them and they don’t have to look down on you. When seated keep your back straight but lean into the conversation. And have your legs out stretched with your legs crossed, this gives a confident laid back look to yourself. When actually talking stand with your legs slightly apart and make your shoulders wider by using wide arm gestures, this also portrays confidence etc. The more confident your stance the bigger you look. Oh and always have a smile on your face
3) When you walk, keep your back straight do not slouch, look keep your head up and when you walk look around and have a nice smile on your face, even nod at people to portray an increased confidence. When you walk, have a slight spring in your step, not a bounce but a confident spring as if you are happy to be out walking etc. Have your arms swinging alternating etc.
The issue with height is purely based on the basis of power, women like strong acting, confident men who has the ability to look after them, which is why they go for taller men. So what you need to do is make them think that you are strong even though you are fairly small.
Hope this helps a little
