Which outfit was your favorite? Would you be caught dead in sneakers in Europe? For me there isn’t an option. We walk way too much for strappy sandals. ha!

I say day 6, just because I have a few shirts similar to that one. I would definitely wear sneakers in Europe if I were walking as much as you did. Like you said, it really isn’t an option to wear strappy sandals.
