The most important rule for every guy would be to buy clothes that fit. Wearing clothing that is too tight or too baggy gives the wrong impression, which is, baggy clothing shortens a man’s torso and tight clothing enhances an unwanted exposure.
Larger MenLarge gutTo conceal a bigger stomach, try to go for darker colors in lightweight fabrics. Avoid baggy t-shirts that hang lower than your pant pockets; instead opt for t-shirts that stops just above your pant pockets. Another helpful tip, wear your pants at your belly button and not below your waist line. The protruding gut is not a slimming effect that displays in a positive light.
Patterns Choose patterns with hesitation. Pinstripes, large prints and pleating patterns draws attention to the wrong areas and in most cases makes you look wider. Try to find shirts the have vertical stripes or look for darker clothing, which slims out your entire frame.
Skinny MenThe best rule for skinny men is to think in proportion with your body. Anything too big will make you look smaller and anything to tight will make you look like your trying too hard.Small upper bodyBecause of your smaller frame, wearing super tight tops shows how skinny you really are. Choose a shirt that is slims; therefore not causing bulkiness and not showing your chest outline. Also, when choosing the right blazer, opt for small shoulder pads. Bigger shoulder pads downs you out while giving you the little kid look.
Break in the colorWearing one color shows your thin frame, so wearing a dark color on the bottom and a light color on top will not show your skinny frame.
Bottoms upWhen selecting a good pair of pants, flat front pockets on a straight cut or boot cut gives you a timeless look while some volume.
Befriend the tailorAs I mentioned earlier, finding the right proportion for your body is very important. If you cannot find clothing that fits you the way that you like, tailoring your clothes is perfect option, especially if you are short and skinny.
Tall MenDressing the bodyBecause of your height, finding clothes that is long enough and big enough will be a huge challenge. Having your clothes custom made or tailored will be some of the few options that you have when buying your clothing. Searching for outlet centers that cater to tall men will be a wise decision. Big department stores, such as Macy's, Dillard's,and Nordstrom (just to name a few) do carry clothing for tall men. However, when searching for clothing make sure that you stay within your body range. So if you are tall and skinny, find items that are big enough for your,but also be conscious of the styles for your skinny frame. And same goes for tall and larger men.
