Ok so I'm majorly requested to make summaries of the future chapters of the season 6 story, so I'm going to give a short summary of what the next chapter will be about. If you don't want spoilers, please avoid this.

Rarity has a new dress to advertise over at Canterlot Carousel Boutique, and she asks Sassy Saddles to model her in the dress for her. The show was so successful that Sassy is asked to model for Fashion Plate for his magazine, but that would also take time away from the boutique.
