I thought it was boring, but Zara's never been a big fashionista. She knows what looks good on her, and that dress fit her perfectly.
I don't like the additional band on the bottom, nor do I like those kind of sleeves, which I guess were meant to slim down her shoulders.
I loved her tiara and hair and make up. She almost always looks fantastic in my opinion (except when she goes for shiny), maybe it's the fact that she always seems to be enjoying herself so much.
All the royal ladies looked great, except maybe for Autumn Phillips - that coat was very boxy and made her look older.
