My wife and I are invited to a Halloween party, with somewhat of an adult theme. Couples are supposed to come in a pair-type costume and my wife had the idea of going as Christian Grey and Anastascia Steele. I'm wondering what you'd all add to the costume to make it stand out.

For me:
I'm going to dress in jeans, a white shirt and grey tie like he does throughout the book.

For her:
A little black dress, one handcuff cuffed to her hand and a masquerade mask.

What else would you suggest? I'm trying to decide if it will work or not.
