The shopping convenience is nice but you know what's even better? How much more informed and understanding the general public is. I remember growing up... a little more than 20-25 years ago... when there were only 2 reasons for a man to wear women's clothes: You were an actor playing a part (strictly comedy of course), Or you were suffering from mental illness.
The shopping is just the cherry on top. The real progress is not having to worry about forced lobotomies.
