Thank you all. Like Angie said, it's done. I feel so much better just knowing what I'll pack and not having to stress about something like this during a time like this. I wanted to get it ironed out over the weekend so I could focus these next few days on getting ready to go.
I'll wear the too-big dress, my trench (which already is void of cat hair, just have to iron it and sew on buttons), and maybe the nude pumps since they are my only closed toe pair. I'd like something more camel (and that fit me better) but I have a back up.
To travel in, I think I'll just wear skinnies, boots, and a sweater to make it easy.
