What to Wear?!

I am having my dress remade for me. My grandma was married in 1939. Both she and my grandfather have since passed away, and I am the last of the grandkids to be getting married. I was given her dress, and then also given permission by my mom, aunt, sister and cousins to do with it as I please. So the current plan is using the skirt of her dress to remake my entire dress. My dress maker keeps assuring me there is enough fabric... We'll see.

For the hubby

Not sure yet. In the entire time we've been dating, he wore a tie once, to one wedding. Not sure if he will wear one to his own though. He will wear a fancy hat, that much i know.  I'd be happy if he wore something like this guys get-up, to keep it casual but nice. really, I love so much about that wedding, I drool over the images.
