That's a lovely idea, but in most Western countries, social mores usually dictate getting to know someone while dressed, before you get to know them not dressed.
Being not dressed does simplify mating rituals, however. I was once told about this tribe of savages... er, "natives"... wherein clothing was either unknown or shunned. A young male's attraction to a particular female is rather obvious in this condition, and when such is noticed, the chief conks their heads together and declares them mates. No dating, no phone calls, no awkward first kiss. Ah, for the simplicity of the Stone Age.
