Once every couple of months Applejack takes a week away from the farm to deliver a large order of apples to Manehatten.

Coincidentally, Rarity is in Manehatten at the same time, showing off her new range of fashion accessories as part of Hoity Toities new summer line. At the opening night party she notices a very familiar looking pony among the crowd.
Could it really be Applejack? The Applejack who is so against "All that frilly froo froo stuff!"
Rarity is determined to find out.
