Would you wear a hat to a wedding?

Since the royal wedding, I've been contemplating wearing a hat or a fascinator to a wedding.  They look like so much fun, and who wouldn't want to feel British for a day?  But on the other hand, I worry that it's a little too attention-seeking for someone else's wedding (that takes place in the United States, where no one is becoming a princess, and at which the Queen isn't in attendance).

What do you think?  Would you ever wear a headpiece at someone else's wedding?  Or is this best left to the Brits?

PS: Bhldn has gorgeous headpieces for brides and guests, and check out this Etsy shop for more Kate-like offerings.
