No. 8 Socks with sandals
It's shocking how many men persist in wearing socks with sandals despite how horrendous it looks. This monstrous fashion mistake could perhaps be forgiven if there were a practical purpose for pairing socks with sandals, but there isn't any. If it's cold enough to warrant wearing socks, then your feet will feel warmer in shoes. And at the beach, getting sand in your socks is simply uncomfortable. The point here is that if you're guilty of committing this heinous fashion crime, do yourself and everyone else a favor and just stop.
No.7 Overt branding
There's nothing wrong with being a label-lover, but discretion is the name of the game.
After all, you'r aiming to look like an incredibly handsome version of yourself, not like a
walking advertisement. Invest in a label because you love the fabric, quality and fit.
Spending your life savings on pieces that feature prominent logos or branding only shows
others that you're more concerned with status substance
No.7 Wearing running shoes outside the gym
Generally speaking, activewear should not be day wear. This rule holds true especially when it comes to wearing running shoes in any environment that's not fitness-oriented. Even if they have no obvious scuff marks, the fact that you wear your runners at the gym during heavy sweat sessions makes it nasty to even consider donning them on any other occasion. For a just-as-comfortable alternative without the "ick" factor, pick up a pair of sneakers or slip-on loafers to pair with your casual ensembles.
No.5 Mismatched suit and shoes
Making a blunder with regard to the color of your shoes practically defeats the purpose of suiting up, which is to look your most presentable. Unfortunately, men too frequently select shoes in shades that don't complement their dress clothes, like brown-hued footwear with black trousers. Follow this advice, however, and you'll avoid this common fashion faux pas: pair black suits with black shoes; gray suits with black or camel shoes; brown suits with brown or camel shoes; and navy suits with black, camel, tan or oxblood-colored footwear.
No.4 Oversized clothes
One of the greatest male fashion fallacies is that loose clothing looks better than more fitted threads. The truth, however, is that even on larger men, body-skimming styles are more flattering. Of course, "body-skimming" is not synonymous with "skin-tight." What we're referring to are clothes that glide comfortably over your body and show your physique to its best advantage. If you're not sure whether you're supersizing your clothes, try going one size down from what you normally wear next time you go shopping and compare the difference. You'll know your clothes are too big if you have trouble discerning your body shape in them
No.3 Buttoning blazers incorrectly
Even with a well-made suit, fastening the wrong number of buttons on your blazer can cause it to pull and stretch in awkward directions, making it seem ill-fitting, so pay attention to the advice that follows. Double-breasted jackets should nearly always be buttoned. With a two-button suit, fasten the top button and with a three-button suit, you have a choice between fastening the top two buttons or the middle one only. And no matter what kind of blazer you're wearing, always unbutton it when you sit down.
No.2 White socks with dress shoes
Teaming white socks with dress shoes may have enjoyed brief popularity as a quirky style statement in the mid-'90s, but there's a good reason this combo has failed to make a strong comeback. Dress shoes should only be worn with dress socks, which are wool or cotton socks in dark hues like black, blue, gray, and brown. White socks, in contrast, should be reserved solely for pairing with athletic shoes and track pants.
No.1 Un-tucked Dress Shirts
Un-tucked dress shirts is a big no-no. We know that you are trying to send a messages that says, "Hey I am trendy and can get all the ladies with my new shirt" but what you are really saying is, "I am sloppy, and I want to covering my beer belly and I really don't care to put the shirt inside my pants. I tucked in shirt goes a long way and you look more put together
