In ponyville boutique "Carousel" everything is beautifull. Tastefully decorated interior, lovingly and carefully sewn outfits that stand on mannequins at the windows and in the hall, attracting visitors.
And, of course, the hostess not inferior to them. A snow-white unicorn of rare talent and generosity, ready to help friends and neighbor, no matter how strange he may be.
One day, an unusual visitor came to the boutique. Looking like a thin minotaur or a long diamond dog, the stranger was polite and courteous. The unicorn had caught a glimpse of him a couple of times in the city, and had even thought of taking one of those wonderful pictures of light that the traveler sold in the market.
The stranger came to Rarity with a question about clothes. According to him, after Ponyville, he was going to go further in the direction of the Crystal Empire, making a detour through through Canterlot and Mainhetten. And the he did not want to wander through those cities in his shabby camouflage. Especially in Canterlot.
The unicorn, understanding the stranger's concern, agreed to help. Having agreed on the conditions of work, pony took measurements from the creature. Wanderer said goodbye and went out. And Rarity was left to estimate and reflect on the implementation of the order. After all, her skill had just been challenged, and she wasn't about to give it up.
After a couple of days, the stranger, as agreed, came for clothes. Some things had to be corrected in small ways, but the wanderer was very pleased with the result. Thanking the craftsmare and paying, he left.
It took Rarity a moment to notice that he had also left a small bundle on the nightstand. Since her name was on the wrapping paper, pony decided it wouldn't be a big sin to look.
Inside was her portrait, as well as the landscape, made of luminous lines. In the enclosed letter, the stranger thanked the unicorn for a well doned job and given inspiration. The master decided to play a little hooligan, and portrayed Rarity in one of the outfits that adorned the mannequins in the hall.
