Black Tux With Brown Vest/Tie

I just decided on black tuxes with chocolate brown vests and ties. My bridesmaids are wearing Jim Hjelm 5665 in chocolate. In the store, it looked kind of sharp and I surprisingly liked it. I have always hated brown and black together and didn`t think that through when I chose my colors....does anyone have a picture of this look? I have googled everything and can`t find one. Also what are your thoughts on this combination? Should I call and change it back to black tie and vest?
