Light Blue And Brown Wedding

Hi. I am having a November evening wedding and I`m having a hard time finding a color scheme. My dress has light blue in it, but I would still like to have an "autumn" wedding. I am thinking of doing light blue with accents of brown. Or maybe brown with accents of light blue. I`m thinking my bridesmaids will have light blue dresses with a brown sash. The problem is, I`m not sure what the groomsmens` vest color should be, as I would like my fiance`s vest to be blue, but I want the groomsmens` vest to be a different color than his. Brown doesn`t look very good against the black tuxedos. Any vest color suggestions, or other ideas of making the groom different in appearance than his groomsmen, keeping in this color palette?

Also, what flowers would look good with this? I was thinking white roses (I really don`t want blue hydrageas!)

I would really appreciate any pictures or websites that have these color schemes in it! Thanks!
