I said she looked like a Pink Lady from Grease, but PT can work too.
And the Grease theme made me think Amy should get on Chris' motorcycle during the wedding and do Cool Rider like Michelle Pfeiffer from Grease 2. The lyrics even describe her man.
"Well, I'm looking for a dream on a mean machine
With hell in his eyes
I want a devil in skin tight leather
He's gonna be wild as the wind"
