Fall Wedding

I am getting married in November and I`m wondering if all the fall leaves and fall themed ideas are going to look as good that late in the year as compared to like September and october. I love that time of the year and I hope that I am picking an attractive theme. My girls are wearing truffle brown and the guys are wearing gold vest and ties with black suits. We are also incorporating ivory, copper and bronze hues in flowers, and decor, but I haven`t the slightest idea where to start with the decorations. Any advice?
