What is corporate clothing?

An easy way to explain what is meant by terms such as office or business uniform is to say that it would mean any garment not worn during time spent outside of the workplace. Each employment sector is different there is no such thing as a comprehensive policy on what constitutes acceptable business wear across industries. In practice, this means that a workplace such as a factory floor or engineering workshop is highly likely to be more uniform orientated than administrative centre for a large blue chip company. In the former case overalls as a minimum are necessary. In the latter case office suits (in the widest possible sense of the term) are likely to be the only stipulation. In principle, business wear can be broken down into several different categories:
Formal business wear:
Formal business wear means dressing to impress, such as when you go for an initial interview, and as such is a cut above what would be worn on a normal day. There is an understanding that going the extra mile in terms of clothing will go a long way to securing the purpose of wearing the smarter suit, in this example getting through the interview process with a successful appointment.
Professional business uniforms:
This would be the normal style of clothing that an individual wears to work. As mentioned above what this means in practice varies across occupations. Many white collar organisations require a degree of standard business wear such a shirt tie and trousers for men and equivalent for women, so that without having to break out the best suit every day, employees still look professional. Clearly, such attire is wholly unsuitable for a mechanic to be wearing as they drain the brakes from vehicles. In such hands on positions, safety is a further additional factor which requires specific consideration when establishing appropriate work clothing.
Casual office or business dress:
In some work environments it is actually counterproductive to wear the proverbial suit and tie, even if the employer is a large corporate organisation. This does not mean anything goes, it simply means that employees do not have to wear a smart suit. Casual business dress means clothing such as a shirt or polo-neck top with smart trousers and comfortable shoes or light boots. Overall it casual wear means functional and conservative clothing with colours that are not overly bright or contrasting and do not clash with each other.
Casual dress:
For people engaged in manual, hands on or trades based employment this not readily apply, the nature of their occupation dictates that some overall or similar garment is worn during their working hours. Many street workers such as fundraisers or market researchers need functional, casual but at the same time professional clothing to efficiently carry out their duties. In office environments, the term casual dress means that employees can dress down for a day and often dress down is intertwined with some fundraising activity. In terms of clothing, casual wear means non-offensive and slogan free clothing such as denim jeans, t-shirt and trainers. In these scenarios an employer is likely to make it very clear that persons who do not follow the terms of what is considered casual wear, will be sent home and then be expected to make up the time to fulfil their duties.
Overall, all of this is meant to impart is that the workplace is exactly that and that no matter the occupation there are definite standards of conduct. It is true that wearing the appropriate clothing is an integral component of employees being able to carry out their duties professionally and safely.
