Can someone, anyone please explain to me this "brown boots" phenomenon?

It seems everywhere I look, women are wearing tall, Princess Leia-style brown boots. Whenever The Wives wear brown boots I make them say, "Please Obi-Wan Kenobi, you're my only hope."

What confuses me most is how brown boots allegedly work with so many different styles of fashion. Dresses, pants, jeans... Reds, blues, blacks... they all work with brown boots now. WTF?

I was under the impression, have even been yelled at by fashion police, for wearing, say, black shoes with a black jacket. Now it's suddenly OK for women?

Please, someone explain how this former fashion faux pas has become the norm so suddenly.
