Floor-length & midi dresses are recommended since the weather may be on the cooler side as the sun sets. Wear any color you wish, but know you are not submitted to a dark color just because it is a Fall wedding. Have fun with what you choose and enjoy showing your personality through what you wear.
Suit and tie are recommended, but feel free to lose the tie if wanted. Bring personality to your outfit with fun socks, shoes, or your bowties / ties. Get ready to boogy!
