Bochur, I am taking you at your word. A girl is forbidden to wear man’s clothes.
It is possible to understand what someone is saying even when he is messing up with the sentence structure. As you will notice, soon after joining the adult world, that a lot of (first) impression are based on written communications. No employer or self-respecting balabos will make contact to a potential employee/hatan who wrote any of your sentences in the latest post. Sad but true. So, you will not get a chance to even demonstrate your wonderful white shirt (unless you attach a photo to the written correspondence). Strunk “Elements of style” is a very thin old book that will help you avoid 90% of errors.
