I am goning to dress up as a guy, can u help me?

Absolutely!

First off, you're going to want to bind your chest to get rid of any unmanly breasts; how you do this depends on the size of your chest. If you're fairly small up top, you can use an Ace chest bandage that you can buy anywhere at a drugstore and wrap tightly around, pushing breasts down and towards your armpits, and then fastening. Or you can wear your tightest sports bra and use duct tape over it (do not apply duct tape to bare skin- ouch!). Even if you don't get as flat as you'd like, that's okay; you can wear loose clothing so it's not so obvious.

Then you're going to want to choose clothing. Go for something rather baggy (but not too big, or you'll look even more girly drowning in a pool of clothes) to give you a bigger looking frame and hide your feminine curves. It's usually a good idea to layer; an undershirt with a polo shirt over it is nice. If you can, wear men's pants, rather than just non-girly women's pants; they'll fit you better and look manly, unless you're aiming for a whole emo/Goth boy in feminine clothes look. If you can, find tennis shoes that give you a little height; the taller you look, the more like a guy you'll look, too. Experiment with different styles- that's the fun part! And don't forget to stuff a sock or two down your pants for that natural 'fill'.

As for your hair, I don't know how long it is, but if it's any longer than your shoulders, it's going to be a liability. With very long hair, you can go several routes: 1) messy and dirty it up with gel, forming little 'dreads' and look like a fun pothead/rocker, 2) slick it back in a ponytail and try to look like one of those tough guys with long hair, 3) put it up under a male wig, or 4) put it up under a hat. A male wig really is the best way, but if you don't have one or don't want to buy one or know where to, it can be tricky. Putting it under a trucker hat is good, but if you have a very feminine face or slender neck, it might make you look even more like a girl trying to pretend to be a boy. If your hair is shorter, you can try various methods. But your best bet is to keep it slicked back, out of your face (no feminizing bangs). Without looking at you, I can't say what would work best; try and see what masculinizes your face.

Lastly, some facial hair really is the best way to look masculine; it's what cinches the look and makes it clear you aren't a woman. Cut off just a little bit of your hair (a half an inch of a lock should be fine) and use scissors to cut them into very, very tiny pieces (it might take a while). You're going to want to get some spirit gum or other 'glue' for your face (ask around), apply it to your face (chin, cheeks, upper lip, slightly down the neck, and sideburns if you want), and then use a blush brush or something similar to 'dust' the hairs onto the glue before it dries. This will create an awesome five o'clock shadow that looks suprisingly well if done right.

You'll want to try and masculinize your face, too- darken your eyebrows with eyebrow pencil (but not in curves- make them a little flatter, while still following the natural arch). Experiment with makeup to see if you can make your face more broad-looking with shadowing.

These are the basic tips I can give you. You might want to consult the following awesome resources:

Good luck!

If you have big boobs, then it will be hard..

cut your hair really really short than spike it

tape your breasts down (sexy), stuff your pants, cut your hair, wear jeans and a t-shirt

LET THE HAIR ON YOUR ARMS AND LEGS GROW.

Put on a Sunday suit with a tie, and some gators

this is a link to a book about a woman who lived as a man for eighteen months, passing as a man. I heard her on a talk-radio show, and what she learned about men was fascinating. Beyond that, she learned how to create a true un-shaved look. She discusses it in the book how she went about it. I seem to remember she used actor's spirit gum (sticky stuff), and finely minced/chopped steel wool that she then patted onto the spirit gum, giving her a definite male appearance. I agree with putting something in your shorts (its called a "cod-piece") but don't over-exaggerate it. Strapping the chest down, of course, and if you have wide hips, try to wear clothes that don't show them. You don't have to smoke, but when you strut your stuff for the contest, having a cigarette hanging from your mouth might help the look. short, short hair. and bushy eyebrows, if you can manage it. (maybe using gel on them, and rubbing them toward the center, and/or up, to "fill them out" a bit?)

When you walk, experiment with leaning from side to side with your whole body. like you have this big mass you are trying to move. When you sit, sit with your legs open, or cross your ankle over your knee only (you have a "big package" down there you don't want to crush, afterall!) Don't talk much, and if you shake hands, get a really good grip and squeeze firmly.

Be assertive, and expect to be in control and looked up to. Take control.

Sounds fun. Good luck. I would love to be able to do it the other way, but I am such a guy-looking guy, it would be next to impossible!

One thing to remember, as you try to walk like a guy, is that men carry a great deal more weight in their shoulders than women do.

That's nothing significant to make yourself ridiculous , time will pass and no one will remember

I made the monitor inclined, repairement needed . The monitor must be at the eye level.
I often avoid thinking, planing when I tried to achieve something. I hate my character, but thinking when "eager to act" is quite "resisted" rather thyan "suffering"

Wear a jacket to hide your breasts you can pad the shoulders to give you a more masculine looking frame.
Wear trousers, one of your father's shirts and a tie will make you look more masculine.
If you didnt want to cut your hair you could hide it under a hat either military/police, cowboy or business - say a trilby.
You could pencil in a moustache and/or apply a grey foundation to your cheeks to make it look as if you hadn't shaved for a while.

Wear a football or basketball jersey. Maybe a redneck looking cap (that advertises Racing), and be sure to put a big can of Skoal tobacco in your back pocket. (However, since your school is probably tobacco free, you'll need to empty the can of its contents)

Oh, and you can't wear make-up!

Just look at a guy and copy him. Wear guy pans and let them hang down to the knees and walk funny.

go with the scruffy look
as short a hair as possible
shade in side boards

Wear pants that are really baggy that show your underwear.

Remember most guys don't think about what they look like.

Imagine you have stuff dangling between your legs and you will be very convincing.

Well I usually walk around with shorts and go on for the day shirtless!

short hairdo, maybe a 2 piece suit with shirt and tie.

wear baggy jeans and a tall tee.

start by learning how to spell going.. Goning?, what the ***** is that. o and stuck a sock in your panties
