My American girls and I went dress shopping to Miracle Mile and we ended up choosing this Priscilla of Boston model:

This is more like a partial check because I still need my Peruvian girls to order it, but they just saw it online and they love it. So excited! I had been delaying dress shopping because of scheduling conflicts, but I'm relieved that finally my girls and I were able to go down to Miami and get it done.
We couldn't have done it without Ursula's help either!
PS: You know you're a knottie when you post your check right after getting home.
