I'm the kind of person who spends all summer looking forward to fall because I genuinely prefer wearing pants to shorts, boots to flip flops and, most importantly, sweaters to tee-shirts.
"Sweater weather" is the only kind of weather I'm interested in, to be honest. That is to say, it's warm enough so you don't need a heavy coat, but cold enough that you can comfortably leave the house in a knit, preferably over-sized, pull-over.
Clearly I'm not the only one who has a passion for fall fashion because this senior cat is so obsessed with his sweaters, he'll literally cry if someone takes one off him. Personally, I'm not that obsessed, but I can certainly see where he's coming from.
