Can this work for formal?

I have two weeks to find a dress for an October wedding (trust me, I did not wait until the last minute to start looking. I’ve just been having bad luck). It is in Italy, dress code is formal, on a villa. I ordered this and it arrived today and I’m thinking with the right accessories and hair I can dress it up?
