When a name doesn't naturally lend itself to an altered form as a nickname, people have a tendency to simply shorten it as a note of intimacy. Thus, one often hears "Mare" for "Mary." With Leslie, I most often have heard "Les," though I suppose "Lee" might due; although I have personally never heard it used for Leslie. (For some reason, in my mind such might seem more appropriate for men with that name than women, though far fewer men are named Leslie than previously. Leslie was originally male but once people started to name girls that, then its desirability for boys diminished. That seems always to be the way. Seldom if ever will parents name a boy with a traditionally female name. Names that have changed genders almost always go the opposite way.)
Some common nicknames for Leslie include Les, Lee, and Lulu.
