There is a delicate balance between standing out and appearing to fit in perfectly

A first impression always sticks and is made in the first 30 seconds. So, when you walk into a job interview, your outfit communicates either your absolute competence or your lack of professionalism instantly. A lot of pressure, I know, but it is true. And sometimes the truth is scary.

It is better to be perceived as above the standard rather than below it. Fingernails, for example, should be clean and trimmed at a minimum. And hair should always be well-groomed, including facial hair for the boys. In most cases short styles or pulled back/ up-dos fare best.

When it comes to clothing and jewelry, research the dress code of the company that you are interviewing for. Any and all suggestions or tips need to be adapted to the accepted attire of existing employees. But here are a few things to keep in mind and should be generally considered appropriate.

Body jewelry, though widely accepted, should be taken out. This goes for ears and anything that might show through clothes. Only wedding or college rings are definitely acceptable, all others are risky. Fashion jewelry included; some like it, some don't. Better safe and simple than annoying and sorry.

A white, long-sleeved dress shirt, professionally pressed and fitted well is always well received on both sexes. And if a suit paints the right picture for the interviewer, go with a two-piece dark gray or a dark blue. Classic, conservative, and chic all at the same time with your color palette being complimentary.

On guys, go for a plain colored, non-distracting, necktie made of 100% pure silk. And use the thick, wide and triangular Windsor Knot. A classic silver tie bar is also a good idea. It will ensure that your tie is held in place during the interview. Without one, you might look nervous with all the adjustments.

When it comes to belts, socks or hosiery, and shoes, go old school. This means that the belt matches your shoes, and the same with socks. Hose should be dark, in black, gray, or brown. Black is typically best on all of the above. And without exception a clean, polished, and conservative look is the goal.

Take along a briefcase or leather portfolio with a notepad and a pen for any notes you may have to take during or after the interview. For the ladies, leave the purse behind if at all possible, both will be too bulky and most necessities should fit just fine in the aforementioned.

Put your entire ensemble together the day before, and try it on. Especially if you are not used to wearing the type of clothes that are appropriate. It is better to feel a bit awkward the day before the interview than on the of.

And last, but definitely not least as it always goes, make sure smell your best while keeping perfume and cologne to a minimum. Chewing some gum before your face to face is also a good idea, just remember to get rid of it before you walk through the door.

There is a delicate balance between standing out and appearing to fit in perfectly. And it is important to keep in mind that at a formal job interview, the most important thing you want to project is confidence. Ultimately, it is your future; so, every effort that sets you apart from your competitors is worth making.
