Wear vertical stripes
Anything that elongates your height is a good thing. For example, vertical stripes in clothing can help extend the look of your shorter body. Patterns such as pinstripe, chalkstripe and herringbone also offer that "vertical" effect.
Note: Steer clear of plaid and checkered shirts.
Wear one color
Wearing a shirt and pants in the same color will prevent obvious breaks in your natural frame, and as a result can give the illusion that you're taller.
Opt for dark shades & light fabrics
In addition, dark colors, especially black, tend to have a slimming effect and help shorter men seem more elongated. The same applies to light or medium-weight fabrics. Heavier fabrics, on the other hand, tend to make you look bulkier and shorter.
A proper fit is key
Finally, remember that it's important that your clothes fit flawlessly. Looser garments can make you look stumpy, so opt for a fit that is trim rather than baggy.
The clothes that'll do the trick...
One way to elevate your stature is by wearing height-increasing footwear or apparatuses such as lifts, thicker insoles, elevator shoes, and shoes with thicker soles. These can all easily add a few inches to your height.
Shopping tip: When shopping for shoes, try sticking to bulkier styles so that your feet don't look too small.
Avoid wearing blazers and cardigans with more than three buttons because they will draw unwanted attention to your shorter upper body. Also, make sure that your blazers and jackets fall slightly below your buttocks, as this will make your body look slightly more elongated. While you should try to avoid double-breasted suits, if you do choose to wear one, do up all the buttons (including the lower ones), as this will give you a longer look.
Also, when wearing a sports jacket, make sure there's as little contrast between your jacket and trousers as possible, to maintain the natural vertical lines. Center and side vents also add the effect of a prolonged vertical line.
In terms of sweaters and T-shirts, V-necks can help make your torso look longer. Turtlenecks, on the other hand, can make you look stumpy, as they conceal your neck.
Look for formfitting shirts in order to avoid excess fabric when tucking them in and opt for point collars instead of spreads. Finally, keep in mind that tucking in your shirt can place the emphasis on your legs and torso, which might make you look shorter.
Shopping tip: Shortening the length of a shirt is generally easier than reducing the length of its sleeves, so make sure the shirt fits properly around your shoulders and body, first and foremost. If it does, then you can have the overall length and the sleeves adjusted.
Do not wear your pants too high; you should wear them just above your hips. Also, avoid wearing low-rise pants (even if they are the trendier alternative), as they tend to make legs look shorter than they already are.
Furthermore, avoid any kind of puckering around the hips, from tucking in your shirts or having full pockets, as it will make you look wider and hence, shorter.
Your trousers should break on your shoes slightly more than average, to help make your legs look longer by covering your socks properly.
It's also suggested to shun cuffs altogether. If you do decide to wear them, have your tailor hem them slightly narrower than normal (that is, 1¼ inches instead of the usual 1½ to 2 inches). Finally, keep in mind that pants with no pleats or a single pleat are more flattering than multiple pleats.
Shopping tip: If you can't find any pants that fit properly, you can always have them custom-made or visit a specialty store near you.
When it comes to accessories, shorter men should avoid bow ties. Instead, they should wear narrower ties; solid, and regimental and diagonal patterns work best. Also, choose the less intrusive four-in-hand knot over the bulkier Windsor variety.
When buying a belt, remember that you can have it adjusted to any length by simply adding more holes. A belt that doesn't have holes is even easier, as it's fully adjustable for a perfect fit.
Finally, keep in mind that suspenders can emphasize your natural vertical line, so avoid them.
Shopping tip: Again, you can find many stylish accessories in special catalogs, at local specialty stores, or in the boys' section of larger department stores. If you're having trouble finding socks that fit, you can always give the socks in the women's department a try.
