I read Angie's sage advice about buying times for the summer season, and was wondering, for those of you who live in muggy climates (GTA, Montreal, East Coast of the US, etc.), what kind of tops do you wear?

I love crips and clean tops, and would prefer not to default to the tank + loose cardigan formula. That said, it seems impossible to wear a white blouse without sweating through it entirely before you reach your destination. Is there something I'm missing?
