This is very important too. There re so many restrictions in a life of a person from his childhood. That is they should wear some uniforms in their school days and they are restricted to wear colour dress like that. Then in their college days, they have some restrictions depending upon the gender. In addition, after moving with all these they are entering into the company. In that, they may have uniform or they may not. That depends on the management.
We should be in formals everywhere. Actually, it does not mean that they have to do always. However, they should act accordingly inside the management and its regulations.
