Questions & Answers about Tu portes un beau parfum, mais sois aussi élégant !
Why does the sentence use sois instead of the normal 'you are' form es?
sois is the imperative (command) form of être (to be) for the tu form. To tell someone to 'be' something, être does not use its regular present tense. It changes completely to sois (for tu), soyons (for nous), or soyez (for vous).
Do French speakers really say they 'wear' a perfume?
Why is beau placed before parfum?
Does élégant have to agree with anything, since it is a command without a subject pronoun?
Yes! Even in a command where the subject pronoun is hidden, adjectives still have to agree with the person you are talking to. Because it is élégant (masculine) and not élégante (feminine), we know the speaker is talking to a man.
