For me the less clothing the better.
Women can hide a lot (gut, rolls) underneath those layers of clothing during winter.
Prolonged periods of cold winter weather can cause weight gain.
I have witnessed this with my own eyes.
This girl I know from my old neighborhood, she was looking fine as hell one September then when April came around she was not looking so nice anymore.
Neither really, that all depends on the women. Chicks wear less clothing when it's hot and staring them from a far can be fun, but they get dirty, sweaty and smelly when you take a closer look. During dark and cold winter you will have a good enough excuse to stay at home, where you can cuddle up close to each other to keep warm. You can also do a player move, throw clothes far away from the bed and turn down heating, chick will never leave the bed and wrap all around you like a snake...
When I was around 5 or 6 my neighbor across the street during the summer would wash her car wearing tiny little tight shorts and a tiny little tight t shirt.
I may have been very young at the time but at that age I could already appreciate hot chicks
