We all make fashion errors now and again, but several fashion mistakes made by men are just unpardonable and downright illegal. Based on personal experience, I have summarized eight common fashion mistakes by men to shun at all costs.

Socks with Sandals - Who decided this was okay in the first place? Living in the Northwest, I am unfortunately faced with some of the worst offenders of this foremost fashion crime. I understand that when it is chilly outside, we all dream of the heat of the summer sun, but sporting socks with sandals doesn't make the seasons transform any quicker. If you want to wear sandals this badly, travel to a hotter environment.

Novelty Ties, Shirts, Boxer Shorts, Etc. - Just say no. There is nothing lasting about novelty clothing nor does it send off a fashionable, put together representation. Leave the smiley faces, hearts, shamrocks, animal and various other prints on the racks of the store where you found them.

Loud Designer Labels - This is a personal pet peeve of mine. I don't fancy being a walking billboard and neither must you. It's not a sophisticated look. Just because you are wearing a designer's name on your chest, sleeve, or anywhere, doesn't make you stylish. Keep it understated and simple.

Backpacks at the Office - I work in an exceptionally expensive apartment building in New York, occupied with lawyers and other professional sorts, and it never ceases to astonish me how many men wearing fine suits are carrying backpacks. Unless you are a student or are hiking up a mountain, leave the backpack at home. If you require something for your gym outfit, buy a nice looking gym bag (and there are alternatives that don't have huge emblems on them), or if you need something to carry your assorted papers, cell phone, day-planner, etc., get a nice messenger bag.

Thick Shoes - These were okay back in the 90s, but the big squat shoes, especially those with square toes, should be retired at this point in time. Choose something classic that stands the test of time.

Shiny or Glittery Shirts and Suits - If you are looking for something to go out nightclubbing in, I can imagine much improved choices than those that are glittery, shiny and ultimately tacky. If you are at a loss, try a form fitting black t-shirt or black dress shirt which can be worn with jeans or trousers and dress shoes or casual shoes.

Clothes That Are Too Loose Fitting - In a word, shoddy. Unless you are a hip hop artist, it's not the right look. Pick clothes that suit your body. This might take some experimentation by combiming and matching certain cuts and styles until you discover the correct fit for your body that is suitable.

Unflattering Colors - That gorgeous navy cashmere sweater you found selling at knockdown prices after Christmas at your local retailer might be truly enticing, but if it makes you look ill, it's no bargain. You should pick the colors you wear to flatter your natural features such as your eye color, skin tone and body shape. Keep this in mind when putting your look together.
