Fall wedding guest dress find for under $200. Michael Costello always has the most beautifully structured cocktail dresses. This periwinkle blue lavender color might be my new fave (sorry pink) and is perfect for a Fall wedding guest dress. Just throw a cute blazer over the top for the ceremony. Size down for the best fit. michaelcostello fallwedding revolve @revolve revolvearoundtheworld fashionbloggerstyle LTKstyletip LTKSeasonal LTKwedding
