This might be Impossible without my picture...you can tell me if that is true!

My niece is getting married. In August. Outdoors. In the South. Are they crazy??

I want a new dress, although I don't really need one. I have a few that would do, that no one in the family has seen. So new would just be to make me happy, not for any other reason. But...there are big issues.

1) August. Outdoors. In the South. I'm thinking natural fabric, loose and flowy.
2) but I'm 53 and I don't want to look like a hippie on a beach vacation.
3) the wedding is going to be pretty casual and I don't want to be overdressed, but...see #2.
4) this is not a fashion crowd, so something that might jump to mind such as a maxi dress wouldn't be recognized as trendy, it would just read as #2 above!

Any suggestions?
