I thought Chelsea looked so pretty in her dress, and it's so jarring to see her like this, because I still remember her as an awkward pre-teen. It's wonderful that she grew into her looks and is now clearly confident and happy.
As for Hillary, I have only seen that one photo of her in the MOB dress, but thought the color looked great, as did her hair (something Hillary has been up-front about having a lot of problems getting right). The caftan was just so surprising to me because it is SO different from anything I have ever seen her in.
Mac, regarding the price of the wedding, I actually read that the estimates were off and the wedding cost less than $1 million. Regardless, I do agree with Julie that a wedding is, in part, dictated on your bank book. Of course you are right that many people spend more than they can afford for their weddings, and require years to pay it off. But that's clearly not the case with the Clintons, so if they can afford it, I don't see it as inelegant if they decided to spend that much on their daughter's wedding. I'm also sure that a significant sum of money was spent on security (despite the fact that the Clinton's have secret service protection), which is something most people don't have to deal with. A tiny wedding/elopement like JFK Jr's isn't for everyone, so if Bill and Hill wanted to go all out for their only child's wedding, I don't find that tacky.
