The color burgundy immediately comes to mind when I think of fall. While fall is still taking some time to really come out of its shell (it's been over 80 degrees almost all week here), this dress blends the best of both worlds. It's short sleeved and comfortable, yet will transition into fall very nicely because of the color (plus, it has pockets!). It'll look great with tights, booties, and a jacket.
