        “To be practical, clothing must be comfortable, and must not inhibit free movement.  If you were cold, you could simply drape a quilt across yourself—and it would be an effective way to keep warm—but it would cause you to be unable to move with any grace whatsoever.  Only the wealthiest and poorest of ponies wear clothing that does not fit them correctly.”  Seeing the confused look on Twilight’s face, she elaborated.  “Poor ponies have to wear hand-me-downs, you know that.  Many of the wealthy ponies in Canterlot dress in designer clothing which was never meant for them, simply to impress.”  Rarity shuddered.  “Why, I remember seeing a mare at the Gala who was wearing a dress saddle that chafed her wings—one could see she was losing feathers.”  She tapped the illustration of the peplos.  “Now that I have seen the creature’s form, I can accurately describe this garment.  I know the its proportions, so I know how long the garment is, and what it is.”
