Not! Well, maybe.
Here's what I find amazing after 18 years in Sacramento: The minute a weather forecaster even hints at 90-plus temps, offices (including mine at 21st and Q) put their workers into indoor deep freeze.
Right now, I fear frostbite on my extremities is a real possibility!
Then, just as I began drifting into sleep (one of the first signs of hypothermia), I discovered the ratty black sweater that's been a constant on the back of my chair since, well, 10 years ago. It felt good tucked around my shoulders until I realized I looked like Grandmamma from "The Addams Family." The poor sweater sort of resembled a well-worn bathmat.
So, I'm going to bring in a cute cardigan to get me through the cold office days. If you've been leaving a sweater at work for days/nights when the AC kicks in full blast, check to see if it's in need of replacing.
Believe it or not, cashmere (it doesn't have to cost a bundle) will keep you insulated but not hot, like wool. Or, a cotton button-up version in a neutral tone will work.
Then, take it off when you exit your office in the evening and watch the hair on your arms stand up when you hit the heat!
