We're having family photos taken by a lake in October. Our photographer advised us to wear long sleeves and to stay away from red, orange or yellow (since the background will be those colors, I guess those colors would either compete with it or we would blend in too much?).

I'm pretty sure I'm going to wear this dress with the gold leaf pendent. I'm a little stumped on how to coordinate everyone without being matchy matchy. Does that gray sweater work or should my DH go for a darker gray or even black? Should our 4 and 1 year old girls match or have different colored dresses? Is the navy blue too dark?

Style is not my thing. Any advice would be appreciated!
