For late Summer/early Fall, one of my go-to weekend outfits is an easy sundress and denim jacket. That way, my Summer dresses can be extended into the Fall season when the weather is just a tad bit cooler.
Not only that, but this outfit is perfect to put on in a hurry. You just need the two pieces-- a dress and jacket (or blazer, even), some accessories, and a lovely pair of shoes. Easy.
And add a hat if you didn't have time to fix your hair. :)
