A Word for a Pretty Innocent Girl

[Lafayette]

I'm having problems find a word for a Pretty Innocent Girl that sounds French. I have seen and heard this word before, but can't remember how it is spelled. I've tried dictionaries and thesauruses to no avail. The closest I can get is immogene.

Please help.
