My headcanon (dress) of new gen5. I was thinking about ponies living in different worlds depending on their kind.  
I’d like unicorns to live in this sort of mystical world filled with more unordinary magic and everything could be a little bit darker.  
Pegasus would live in the world that would look like ancient greece and it would be more nobel.  
I’d like to see earth ponies in some kind of late 18’s our world. When I was thinking how I’d like to dress Sunny I thought about Jane from Tarsan :)
