I guess it would depend on how close you are with the wedding party. It is also hard this time of year because you just don't know what the weather will be but, depending again on where you are that could set the stage. If you had a simple dress or skirt with a jacket that would do. I say mix and match where you can. Again, taking in consideration that the wedding was not Black&White. Which of course would mean it was totally formal. So, take what you need and move from there. I hope I helped.
