In a place like Florida wearing a heavy scarf almost any time of year is crazy! But a beautiful lightweight silky Missoni Scarf didn't seem like a crazy idea when I got one......but how do I wear it???
i think all above options sound good, that's how i wear scarves as well! also, how about just swinging it around your shoulders really loosely and wearing it as a "wrap" when it's night time and you don't want to bring a sweater!
