Need help picking a dress!

Audra • 23 years//God bless this hot mess

So my boyfriend JUST informed me we're going to a wedding... tomorrow. It's a casual barn wedding, but I'm not sure what even looks remotely appropriate to wear to a fall wedding. Would any of these dresses work? I'm afraid I might not be able to get to a shop in time to get a new one!

Or any tips on where/what to look for since I'm in a bit of a time crunch here! tyia!
