how would i say "look pretty" in vous form?

You are pretty = vous êtes belle

Sra (aka Mme)

how do you do

vous êtes jolie = rather than you are beautiful, this says "you are pretty."

Sometimes you simply have to accept that you can NOT say exactly the same thing as in English. There is a verb "to look like" = ressembler à, or to seem = sembler. Perhaps the very closest you can get is "vous avez l'air d'être jolie" (you have the 'promise" of being pretty)

Sra (aka Mme)

To say "look pretty" in the vous form, you would use the imperative form in French. The imperative form is used to give commands or instructions. Here's how you would say it:

1. Start with the verb "look" which is "regarder" in French.
2. Conjugate the verb "regarder" in the vous form. In this case, the vous form is "regardez."
3. Add the adjective "pretty," which is "joli" in French. Since "joli" refers to something singular and masculine, you need to change it to its feminine form, which is "jolie" to agree with the subject.

Putting it all together, "Look pretty" in the vous form is "Regardez jolie."
