When Did It Become Fall?

Remember the SATC episode where Charlotte asks, "When did it become Fall" and Carrie removes a perfectly folded blanket from her dresser, curls up in it and you can actually feel how calm and comforted she is though the TV? Well, when DID it actually become Fall.

When did I begin sipping pumpkin spice lattes and fall (ha pun) into my Winter work wardrobe consisting of solely leggings (or jegging) with boots, a tunic, an oversized sweater and neck-engulfing scarf?
When did shopbop post their Fall 2010 Trend Report?
When did Katie and I begin discussing which Halloween masterpiece to execute this year?
When did JT$ begin loving fashion again?
When did a standard Saturday ritual change from making hair appointments for weddings to spending the morning trying to find my issued UW arm band?
When did it become ok again to not be productive on a Sunday and sit on the couch all day watching football?
Most importantly, when did my wardrobe all of the sudden become (gasp!) outdated?!?
