Dress for a second reception

We're having a second reception in Omaha a month after our wedding for all of FH's friends and family that couldn't make it to the LI wedding. I'm not going to wear my wedding dress, and FH is not wearing a tux- likely just a suit for him. I'm kind of at a loss for what to get. Should I do just a short white dress or a cute cocktail dress with a lot of white in it?

I'm curious to see if anyone else is also having a second reception!

Something like this?

STEPH!!!!
Personally, I love the first dress!!!!
We're doing something in Kansas, but i havent even begun to think about what i'm gonna wear to that.... My only thing about the first one is that is it a little over the top for Omaha, cuz i know that would be too much for the one we're doing.
But i love it!
