Anchie, I think that some of our preferences never change, some are fluid, and some change completely - Your boot progression has adapted to the changes in your life quite organically. Makes sense.
To latch onto what Suz said, our lifestyles, age, hair colour, context and climate can cause major changes in sartorial preferences.
I've hardly ever worn black shoes - not even in the '90s. This has not changed.
I've loved the same types of colours, and white pearls since I was a child.
I used to wear a lot of dark blue. Then switched to black. Am back to dark blue and not switching again.
I used to wear a lot of gold. Then switched to silver. Am back to gold and not switching again.
I used to wear 2 inch heels more frequently. Even threw in a 3 inch pair for weddings. Now I don't go past 1.5 inches, but am in one inch or sneakers daily.
I used to gravitate towards maximal playful and pretty outfits. Then I switched to a minimal and strict androgynous vibe. I switched back to maximal and pretty.....and am staying put.
I've always loved '60s, '70s and '80s style!
I used to love wearing belts. Now I don't
I NEVER wore corduroy pants as an adult. Now I do
