First impressions count, and although it may seem superficial, the way a candidate dresses has a huge impact on whether or not a prospective employer will take them seriously. The obvious route would be to go for the standard two-piece suit, with a shirt and tie, but if worn incorrectly this could be as much to your detriment as turning up in ripped jeans.
Dressing for an Interview
The most important thing when dressing for an interview, or for any other occasion, is to make sure that you are comfortable. Don't take this literally of course, as pyjamas are very rarely suitable for interview situations. What we mean is that the way you dress should reflect you as a person. If you never wear a suit in your everyday life, putting one on for an interview might make you feel awkward and uncomfortable, which can have a much more negative effect that turning up in the smartest version of what you feel comfortable wearing.
The next most important thing, is to make sure you know your audience. If you turn up to an interview in a smart shirt and jeans to be confronted by a panel of people who look like they grew up on Savile Row, then you can feel like you're already fighting a losing battle. Likewise, turning up in a three piece suit and dicky-bow to an interview at a design agency makes you seem like you don't understand the environment you'll be working in. Do your research and try to gauge what level of smartness is required, as something as simple as this can immediately show that you understand the business that you're trying to get in to.
What to Wear
As we've explained, exactly what to wear depends completely on you and the job you're applying for. One thing we would extol the virtue of, however, is the plain white shirt. This is the Swiss army knife of any man's wardrobe, the male equivalent of the little black dress, ready to be dressed up or down for whatever the occasion calls for. Because of this, you might find that they're worn a lot more than other items of clothing, giving them much more opportunity to pick up stains. Additionally, the very whiteness of the shirt makes these stains far more obvious than they might be on a coloured or patterned shirt.
This may make it seem like the lifespan of these shirts is slightly shorter than you'd like it to be, but this doesn't have to be the case. As soon as you notice a stain, try and wash it out (from the back) with some warm water, don't scrub it as this can cause the stain to spread. Then use some Vanish Gold Oxi Action Whitener + Stain Remover Powder on the affected area, gently massaging it in and leaving it to work for the allotted time. Then simply wash the garment as you would normally with a scoop of Vanish along with your detergent. This will not only ensure that the stain disappears, but it takes care of the rest of the shirt and sweat stains, leaving the garment dazzlingly white.
Stating the obvious, but this can make all the difference.
When you're confident in what you're wearing, you automatically give off an air of confidence. So get in there, and get the job you deserve!
