White on a Friday Night?

In October? 

I really want to wear a white cocktail dress to our rehearsal dinner on Friday night.  

Something like this:

**I think this one needs to be a couple of inches shorter, at least to be flattering on me. I recently saw it in a bridal magazine and it was much shorter. (not slut short but a more flattering length)**

Or something with a fun ruffle:

Love this one, too. Classic.

I've also considered something in a Champagne color as a nice alternative to white in the fall. 

You might recognize this from this post... At least my taste is consistent.

Speaking of the navy dress that I would love my bridesmaids to rock... I also love it for engagement pictures. So, maybe I will buy it and resell to my bridesmaid, LOL. Or keep it because I love it!

 I also really like this. Perfect for a cool fall evening! But is it too casual? With some killer heels? 

Thoughts on white on a friday night? For a bride?
