WILL MARK BRAINLIEST I am practicing spanish and I need to use the tu' positive form to say something like:
"wear work clothes" or "wear appropriate clothes for work" (or something like that)
please don't put this into a translator because it does not help, only answer if you have learned tu' commands and know how to say this.
also if you have extra time please tell me how to say "Don't talk when your boss is talking" in the negative tu' command form.
