In the winter I always walk about wearing an absurd amount of layers and looking as though I am about to embark on an expedition to the Arctic. I think this sort of effects my personality and the way I behave in those months. What I wear always has an effect on me in that way. I feel like I'm not myself in the winter.
It isn't until April when the multiple layers of clothing are no longer needed that I act like myself again.
I'm a lot more functional too. Wearing less clothes makes me an effective human being.
