What are modern-day definitions of ladies and gentlemen?

If a man or a woman does not fit the stereotypical images of a gentleman or lady (respectively), are they any less of either?

At least three times in my life I’ve been asked by the same person, “Why do you want to look like a man?” The first time I was caught off guard. The second time I reacted angrily. The subsequent times, I shrugged it off and said, “I want to look like me.” Does having tattoos and short hair minimize my femininity and take away my status of a lady?

Considering the wide spectrum of beliefs regarding gender identity and expression, and the history of the terms ”lady” and ”gentleman,” what are the plausible definitions for modern-day ladies and gentlemen?
