There are some simple ways a man can dress to look taller, and the formula for dressing taller isn’t really that difficult to learn. It’s just a matter of sticking with a few rules when buying clothes.
Wear Close Fitting Clothing: A loose fit on a short man actually emphasizes his petite frame and it makes him look sloppy. It also signals that he’s too small to find clothing that fits him right. Don’t let your own clothing send this message to the world. Always pay close attention to where your clothing sits on your body when you try it on. Most men are used to wearing clothing that is 1 to 2 sizes too large on them, and smaller men who have never given it much attention are some of the worst offenders. Steer clear of jackets that hang loose in the armpits, even if the sleeves are short enough for your arms, and avoid any trousers with a lot of slack cloth in the crotch.
Wear V-necks: These dapper gents are all sporting cool as hell v-necks, which elongate the neck and give the illusion of length. The deeper the V, the better, but don’t go crazy.
Don’t wear short sleeves: So much of what you wear creates an optical illusion, and one of the weirder ones is that short sleeves will shorten your arms. If your arms look short, so will the rest of you. Instead of a short-sleeved button down then, wear a long sleeved shirt and then cuff the sleeves. This will create an unimpeded line that will make your arms, and as a result your body, look longer.
Keep accessories simple: In order to appear taller you want the eyes of whoever’s looking at you to sweep upward. The more someone’s eyes sweep upward, the taller they will register whatever it is they’re looking at. And to maintain that upward sweep, avoid anything that will draw their attention below your chest. Steer clear of flashy shoes, flashy watches, and big belt buckles (actually, you should try to avoid belts altogether). And if you absolutely have to have some flair, maybe go with a hat or a bright pocket square. But just remember this mantra: The lower you go, the simpler, and darker, you should go, too.
Choose the right pattern: Stripes elongate your frame probably more than any other pattern. The trick is to make sure the stripes are proportioned to your frame size. A very wide stripe on a slender frame can actually make you look smaller. When it comes to plaids and checks, stick to smaller ones. Big patterns will swallow you up.
Keep your shirt shorter: A shorter shirt will add more balance to your body and keep your proportions in check. A too long shirt will make it look as if you’re wearing the wrong size or someone else’s clothes. Anything long will swallow you up and make your legs look stubby.
Avoid vests: Vests can make you look shorter by drawing attention to the middle section of your body, and away from the overall long lines of your frame. If you really want to wear one, stick with one that’s the same color or pattern as the rest of your outfit.
Monochromatic color : Along the same lines as minimizing visual clutter, removing contrasting color from your appearance helps streamline the way you look. Keeping all your clothes within a fairly consistent color theme, especially a dark one, will create an illusion of height. Different color shades are fine but just try to keep it loosely monochrome, when you do wear different colors or different shades of the same color try to weight the darker color toward the bottom half of your body. That way people’s attention starts down near your feet and travels upward. Dark trousers with a lighter shirt create a lengthening effect; a darker shirt with lighter pants shortens your appearance.
