I'm joining in!
* You and your DF sound just like me and my DH! Like you, I love to read (I'm in school right now to become a librarian), and I'm a HUGE Harry Potter fan! My DH is a computer programmer who loves Star Trek and video games

* Love your ring! The tanzanite stones are so pretty, I got a pair of earrings with tanzanite on my last cruise. Sadly now my ears react badly to earrings and I haven't been able to wear any earrings at all in the past few years.
* I agree with you that at least for me, $450 is more than I would pay for a dress. There are some really nice ones out there for a less, and even though it's a once in a lifetime dress it's still a dress you're only going to wear once. I got mine at DB on clearance for $250.
* Love the Malibu blue!
* Yes, another Ravenclaw (I don't care what Pottermore tells me)! My wedding colors were royal blue and silver

* What a horrible doctor! I hate driving, but it is a necessity where I live. I didn't get my license til I was 22 though.
* I'm so glad you got your dress!! It looks nice in the picture but I'm sure it will look even more lovely on you! I feel like the girl in the DB picture has a really weird, hunched over pose that makes the dress not look as good!
