How do you say can I see you naked in french?

Answer 1

Can I see you naked ? = puis-je te voir nu (to see a man) or puis-je te voir nue (to see a woman)

Answer 2

A colloquial variant would be "Puis-je te voir à poil?" where "poil" means "body hair" as opposed to "cheveux," which means "hair on the head." A colloquial variant for "sunbathing naked" is "fesses à l'air," which means "cheeks in the air."
