I agree that she doesn't look all that happy in most pics, but because I don't know her, I can't tell if it's just the stress of a very public wedding, if she's not normally smiley, or if she really did want to escape.
I totally agree. I think she looks extremely tense before the ceremony, but she loosens up after. There is a nice picture of her and Albert talking together as they walk back up the aisle.
Naomi Campbell's dress for the reception, was IMO, entirely inappropriate.
Thoughts?

That dress is horrendous. It's sole purpose is to scream "Look at meeeeeeeeeeeeeeee!"
The fact that it's white bothers me less, because a lot of guests wore light colors, including Princess Stephanie and Princess Victoria, I think.
I have another O/T question: why is Prince Edward wearing white military regalia? I noticed that most, if not all, of the royal men wore white - but Edward has always been one to prefer regular clothes to uniforms, including at his own wedding, and recently at William's. I really don't remember any recent event where he wore uniform, especially not white - I didn't even know that there were white uniforms in the British army.
