When the sun's blazing and the air conditioner's blasting, lightweight summer sundresses hold great appeal. But if you can wrench your thoughts away from staying cool long enough to look at a calendar, you'll realize that Labor Day and
back to school are just a few weeks away. And that means falling leaves and cooler temperatures won't be far behind. So while you're enjoying the remaining dog days of summer, you may want to trade your sun visor for a proverbial Fall thinking cap. Using your imagination, and a few layering devices like
leggings, cardigans, long-sleeve tees and turtlenecks, you can easily transform summer
dresses into go-to fall frocks. Just click the slideshow to see a selection of
vintage dresses that make excellent presto change-o finds!
