Fall dresses are perfect for the days when it is cold but not too cold. They can easily been warmed up by tights or boots, but the days when you can just wear them with a light jacket are the best.
This one (Old Navy color Burgundy) is perfect for the holiday season (especially Thanksgiving coming up). It is very flowy so it hides whatever you want it to. I threw on a faux-leather jacket (old) and ankle wedge boots (DSW) to dress it up.
This dress is also great for everyday wear or if you have a casual office you could wear it then too. I find that this style is easy to throw on and either dress up or dress down.
What are your plans for Thanksgiving?
