Just a thought, but doesn't perfume attract mosquitoes? I was actually planning on leaving mine at home because of that fact (plus, mosquitoes LOVE me to begin with).
That being said... don't laugh... Off! insect repellent comes in a pretty nice "tropical fresh" scent (part of their FamilyCare/Skintastic line). Its melony/tropical. I wouldn't call it "perfume"... but it's really not bad. And, frankly, anything I can do to avoid a bite...
But, for light and fresh I highly recommend Bulgari's Tea collection (white is my fave), and the Issy Miyake is nice for the boys.
