As I mentioned here, layering this necklace over a collar buttoned up all the way has become one of my favorite little details to spice up a simple outfit. And you can't get much more simple than denim on denim. (See some of my other Canadian/Texas Tuxedos here & here.)
As for the braids, I periodically get obsessed with maiden braids and I've been on a major kick recently. In fact, I learned the other day that my hair is actually long enough to do a whole wreath (not just over the top as I'm wearing here). I've been waiting for this moment since I was 8 years old and saw Leia's braided wreath in The Empire Strikes Back for the first time. I must say, I feel like I've accomplished something big.
I think I'll try to shoot a tutorial soon.
