How do you say pretty lady in french?

Tu es très belle is a French equivalent of 'You're very beautiful'. The subject pronoun 'tu' means 'you'. The verb 'es' means '[you] are'. The adverb 'très' means 'very'. The feminine adjective 'belle' means 'beautiful'. All together, it's pronounced 'tyoo eh treh behl'. But if it's a 'beautiful' or 'handsome' male, then the Word becomes 'beau', which is pronounced 'boh'.

That's what's said to someone who's part of the speaker's close circle of family, friends, and peers. What's said otherwise is 'Vous êtes très belle'. It uses the formal 'you are' ['vous êtes'] form. It's pronounced 'voo-zeht treh behl'. Once again, if it's a 'beautiful' or 'handsome' male, the Word becomes 'beau'.
