Men with slim builds should avoid straight leg trousers. Denim washes, however, tend to distract attention away from long, thin legs. Leg enhancing slim fit jeans, on the other hand, look great.
To make narrow shoulders appear wider, choose tops with round necks and patterns, patches, or big logos.
Men with a normal build can more or less wear anything, although slim fit jeans can look a little less flattering since they draw disproportionate attention to the legs. Men with a normal build can, however, wear any tops they please whether with a round or v-neck cut, with patterns, or logos. There is no need to limit yourself to any style!
Men with a bit of a stomach should choose wide, straight-cut tops, since these tend to narrow the figure. They should also avoid big patterns which often stretch out unflatteringly over the belly. V-neck tops are great for making wide shoulders appear narrower. Avoid slim fit trousers which can highlight the stomach further.
