Are Elsa dresses still available in the MK?

We're headed at the end of this week, and doing MNSSHP. My DDs are dying to be Elsa, and I remember seeing folks reporting dresses available in park recently. Still true?

A friend of mine was there a week ago today and they were available in MK. They were about $70-80/ea.

lots of them in norway pavilion at epcot today.

There is a Frozen-themed shop on Sunset Boulevard at DHS. They have Anna and Elsa dresses (plus lots of other Frozen merchandise) there.

Does anyone know if they have them at BBB in the MK? I'm wondering if I should buy one ahead of time or just wait.
