We added a little English flair to our American wedding. We were able to rent morning suits for the guys, but not top hats which DH really wanted. My mom sewed a sixpence onto me "keep" garter. It also had a blue ribbon through it and a pin of a crossed UK/US flags. We got fruit filling in our wedding cake and got our toasting flutes from Harrods.
DH had hung out with my BIL and my cousin's husband, so he had someone around to give a toast since only his mother came to the wedding. He wanted to have the evening do after the reception, but we just couldn't swing both, so we had our reception in the back of a lovely restaurant with an open bar. (We did all get together in my grandmother's room after where she tried to liquor us up some more).
Neither of us were disappointed, I think he was looking for something a little different since it was his second wedding and I was looking for something small.
PS Sixpence you can order on line. I think we got 6 for $6.
