Here are some of the worst fashion mistakes that guys commit all the time. Make sure that you aren't guilty of any of them.
1. Socks and Sandals
As you may have guessed, this one just had to show up on the list. It is almost universally known that you never wear socks with sandals, but guys still do it. It is never a good look for anyone, besides, if its warm enough for sandals, its too warm for socks.
2. Cell Phone Belt Clips
These are so puzzling to me, why is it not sufficient to put your phone in your pocket? Why do you need to keep your phone attached to your side where everyone can see it? If you are one of the guys who still use these phone belt holsters, then lose it; it makes you look quite nerdy.
3. Stained Clothes
Even if you think the stain is small and people won't notice it, change, because I guarantee that they will. If you want to impress people and show them that you are well dressed and sharp looking, then properly clean your shirts and remove stains, otherwise they will think you are a slob.
4. Blaring Brand Names
Just because it says "Louis Vuitton" or "Dolce and Gabbana" on it, doesn't mean it's stylish. Big brand names across your shirt, no matter how expensive the shirt was, look cheap, so leave the brand advertisements for billboards, and not your chest.
5. Ill Fitting Clothes
One of my biggest annoyances is when people wear terrible ill fitting clothes. Anything looks better when it is properly sized and fits your body well. Often people buy clothes that are too big and look like they are swimming in fabric. If this is the case, take it to a tailor and have it adjusted, and make sure in the future to try things on before you buy them.
