I recommend you to try this season the combination of violet and pale apricot colors. I also would combine violet with pink or apricot color with yellow.
I think these colors would look so nice for this fall season.
I know that it's getting cooler and it's not really a perfect time to buy summer dresses, but I like one Russian saying which says: "Prepare the sled in summer, and cart in winter" (Готовь сани летом, а телегу зимой). In this case it means: Now it's time to buy, to take advantage of huge sales!
With Love from Cape May :)
