depends on where you live. yesterday, it was 73 degrees in the Detroit area, and I wore a cotton skirt, cashmere tee, and boots. I was very comfortable. I would wear them based on how comfortable you are. I often wear boots in the summer on cooler days - with jeans or skirts and a lighter weight top.

I'm in NJ. I was playing around with them and they look great with a short denim skirt, but I'm at a loss of a top... I don't want to look like a cowgirl.
