I've known Kristina for probably 5 years and it was a pleasure to design her wedding invitations!
The script typeface is called 'Buttermilk' and I purchased it from a great illustrator/type designer named Jessica Hische.
The swirls were customized from an original set of 'swirls' I had. The secondary typeface used for body copy is Baskerville Old Face. It seemed to go well with the elegance of Buttermilk
