Being self-employed or having your own business, whether it is only small, still requires you to be business-like in your appearance and your actions. This is important so that your customers and suppliers will perceive you as someone who should be taken seriously.
One way of maintaining a business-like appearance is by wearing formal clothes. You are not required to wear suits or coats. Being business-like could mean wearing polo shirts and maintaining a clean and neat appearance. Having calling cards ready to be given to your clients and suppliers can also add to your being business-like. You can have the calling cards be printed using color print which are not that expensive. You can also improve your appearance through your mannerisms and how you handle clients.
