While I didn't follow much of the wedding, I did enjoy seeing Kate's dress and thought that the lace (the rose, thistle, daffodil and shamrock) was very nice and the short train was appropriate.
I also liked the dress worn by her sister, Pippa. I've seen many people questioning that she wore white (or maybe off-white), but I've also learned that the Maid of Honor in GB wears a "matching" dress to the bride's.
The only dress I saw that I didn't care for was Prince Harry's girlfriend, Chelsy:
It looks like she was just "roused" out of bed and threw on two mismatched pieces and a hat.
BTW, what's with wearing your hat on your forehead???
