I went through menopause all kinds of backwards. I had the partial hysterectomy in 2008, now I'm dealing with the hormonal crap.
Layers. This saves me at work. I start my commute with lots of layers, but once I'm working the layers wind up in a pile on top of my purse under the counter.
Lighter weight cashmere. I had a cashmere sweater from Vince that felt like air or clouds, so soft and light and fluffy (even though it was NOT a fluffy sweater).
Looser knits. I have a wool sweater from Free People that is very lightweight and loosely knit. It's not loosely knit to the point of being semi-sweet, but it is close. Not so close that I need a layer under it, though.
Between the hot flashes and working in a 40F room for a year and a half, my internal thermostat has been reset with a higher tolerance for cold and a lowered tolerance for heat. I've noticed that keeping my extremities and ears warm generally keeps me feeling warm enough to wear much lighter weight clothes on colder days at work. Sometimes I'll be wandering around in a tank top and gloves + hat or earmuffs. I am certain I look weird and I don't care. I'm embracing my weird LOL
