Formal:
* Você é muito bonito/bonita. (You are very beautiful/handsome.)
* Você é muito charmoso/charmosa. (You are very charming.)
Informal:
* Você é muito fofo/fofa. (You are very cute.) - This is a good option for a child or someone you are close to.
* Você é um/uma gato/gata. (You are a cat.) - This is a playful way to say "cute," but can also be considered flirtatious.
* Você é lindo/linda. (You are beautiful/handsome.) - This is a more common and versatile way to say "cute" in informal settings.
* Você é bonitinho/bonitinha. (You are pretty/handsome.) - This is a slightly less formal version of "bonito/bonita" and is commonly used for children or romantic partners.
Important:
* Gender: Brazilian Portuguese has distinct masculine and feminine forms for most words, so make sure you use the correct one.
* Context: The best way to say "you're cute" in Brazilian Portuguese depends on the context and your relationship with the person. Be mindful of cultural differences and avoid using overly familiar language if you are not close to the person.
