Well, no one gave the perfect answer because there is no hard and fast rule or perfect answer to dress code. Now, let me tell you about my company. I wear t-shirts, jeans, and chappals, but no one says anything. There is no dress code in our organization, and it is not required. Just because I wear any dress does not mean you can do the same. Also, just because someone mentioned that a dress code is essential does not mean it is.
Industry and Dress Code Considerations
Now, coming directly to the bull's eye, Mr. Asif of Bangladesh, you never mentioned what industry you are in and what type of people work there. Once you mention the type of industry and the work that goes on there, people will be able to give you better suggestions. Additionally, regarding your industry type, you need to mention the severity of the dress code. For some industries, dress is part of the image, as mentioned by Mr. Bhatia. Therefore, in places like McDonald's or airlines, even a small compromise in the dress code will not be tolerated. Hence, post your industry type, and then consider the customized advice given by people. Do not follow any advice without considering your specific needs.
