My wardrobe minimalism project led me to the conclusion that I just can't stand polyester. Toronto summers tend to be very humid and I just can't stand the way polyester sticks to my skin. My entire body tends to be fussy when it comes to these things. I will not completely forego polyester due to my jersey dresses, but I'd like to make an effort, from here on, to purchase anything but polyester. So I have a few questions for you all:

1. Where can one purchase silk button downs - particularly prints?
2. Which brands/retailers sell clothes made of breathable/natural fabric?
3. How do you care for silks? Are they hand washable?

Thanks ladies!
